Need help! Thinking of returning my dog

[oreo]

5 weeks ago my husband and I decided to adopt a dog a month after we had to put our old little guy to sleep. We went to the shelter and we decided to adopt Oreo. We didn't want anything specific. Could be any size and any breed. We knew we didn't want an old dog because of the fact we just had to put to sleep an old dog. And we also needed a dog whom would like cat. Because we already had a cat. So we adopted Oreo. A 6months old amstaf mix (pitbull) beautiful. Lovely. Playfull. We got her everything a dog need and everything she doesn't need either just because. I hired a trainer. A walk her 3-4times a day. I play with her. I train her. I give her kong w peanut butter every night. I crate trained her. Even tho I had to buy her a barking control collar. (It did work, no. It doesn't hurt her)
But here is my issue now. Even after 5 weeks. She doesn't shows like she will like my cat any time. Even training her with a professional trainer she jumps on every simple person who past by next. Sometimes even when they pass on the other side of the street. She barks for 99% of the dogs on the street. When she doesn't bark she pulls. She pulls a lot. It's kinda annoying walking her. It doesn't matter what I do. She doesn't want to learn. She does everything I train her to do IF there's no distraction. And by distraction mean anything. Car. Trucks. Animals. People. Anything.
I know she's just a puppy and I know she has a lot of energy. But it doesn't matter what I do or how many times I walk her. As soon as she gets home. She gets all hyper again. Even when I run her for 40min-1hr.
When we are home. She literally doesn't leave me. I can't even go to the restroom without her getting crazy. And when she gets crazy she starts to destroy everything. And believe me. She has a lot of toys and bones. But she likes to destroy everything that she was not supposed to.
I'm trying everything. I'm trying my best to be patience. I believe the person whom had her before kept her locked by herself. She doesn't know how to do anything. Nothing. Walking on leash. Potty. Crate. Nothing. And I don't mind training. But she seems not to learn. Or just do when she wants to.
I want to be able to take her for a hiking. To the beach. To the park. Dogs park. But I can't. I can't take her anywhere. Because she's not socialized.
I've been trying camomile tea to calm her and help with anxiet. But it's not helping much.
I'm getting overwhelmed and really thinking about returning her to the shelter.
I feel horrible for thinking of it. But it's getting annoying and instead of me falling in love with her. I'm actually falling out of love.
I really don't know what to do. And what worries me more is. Will she be able to ever live with my cat?!
I can't really live with the animals in separate rooms anymore. I live in an apartment. It's driving me insane. And it's not fair with the cat either.
I thought of returning her and maybe adopting an younger puppy. I really don't mind the destruction (until an certain limit of course. But I understand it's a puppy learning kind of thing) so I can actually properly train it. Specially with the cat. And socialize it. so I can be able to take it to the park/beach/hike.
I really don't know what to do. And if u had the patience read it all. Please. Give me some advice.
I really wanted a dog to be my company. A dog I would be able to take to places with me. To cuddle w me watching tv. But with her I can't do non of it. She doesn't even lay down with me without jumping all over and liking me non stop. She doesn't know when to stop.
I really need help. Please!
Thanks.

That's a lot of information to take in.
First off take a deep breath and calm down. You said your dog is about six months old. She is still in the puppy play stage and most likely will not start to mellow down until she is at least a year old. The energy, the destruction, the barking. she is an annoying bratty child right now, testing to see what your limits are.
There are things you can do to help curb the destruction. Most of which I will refer to trainers on the forum a bit wiser then me. One question. When she starts to destroy things you do not like, do you yell, chase her around? If so then you are doing just what she wants you to do. You are giving her attention.

When I was younger we adopted a seven month lab mix. Autum was the definition of destruction. She had separation anxiety like crazy and ended up destroying furniture, clothing, a wooden floor, drywall, and a poisonous Japanese ivy plant that sent her to the vets for an unpleasant night. Most of this was before she was a year and a half. But, she did calm down before she was two. As will most likely your dog.
You need to keep working with her, establish your rules. Head over to the training and behavior section of the forum and look up things like NILIF and a possible shut down period for your dog.

Now about the cat and her around other dogs. The fact is with this breed they do have a higher chance of being dog aggressive and they do tend to have a high prey drive toward smaller animals. This is no reflection mind you that she will end up being aggressive towards people. In fact APBT are known for being very people friendly. I have an adopted APBT mix named Maxine. Around people she is the sweetest most laid back dog on earth. But, despite having her since she was three, and her going on seven right now, she still acts like a nut around squirrels, rabbits and the neighbor's cat. These are things for her to chase in her mind. She is still highly reactive to other dogs. I will never trust her off leash, or in an area were there are other dogs that she can interact with and not have a fence or physical barrier between them. This is just my dog. For me its fine, I don't have other animals and her prey drive keeps the bunnies out of my garden. But it may not work for you.

Just remember that you have a puppy on your hands right now. She will need a lot of work, a lot of structure and will push every button that you have, regardless of her breed. She may never get along with the cat, or other dogs. In fact because of the breed's stigma I would not take her to a dog park even if she did. If something did happen, she would get the blame for it automatically. If you can accept this and put the time and energy into raising her into an adult dog, then hang on for the ride. Otherwise you may want to go with another dog in the 1-3 year range.

Return her. You can't handle a puppy. Do not get a pitbull or am staff.
Either go for an adult dog at a year old or older. All dogs need adjustment time. If you can't give them that return her.
Once people post they are thinking of returning a dog they 95% do.
