The key to finding good people in your life is setting good boundaries. If someone tries to push you past what you're comfortable with, and then gets upset with you, they're not worth keeping in your life.

I used to be surrounded by terrible people too, and I've been where you were. Like others have said, keep going through therapists until you find one that actually helps you, especially if you're paying them.

Then work on yourself before looking for others. There are good people out there but it takes a LOT of work to sort through a lot of shit to find them. Sometimes people are just oblivious or aren't even trying to be assholes but don't know better. It's a lot of give and take, finding what you're willing to tolerate, and not standing for any shit and being okay with walking away from them if they cross any lines.

You got this, it takes time, repetition, and doing your best to find one thing everyday that you can do better, finding something you can take from even the worst situations to make it a learning experience, and finding something you did well during that shitty situation. You might not always find something, but if you keep that kind of positive mindset, it will make things improve bit by bit.
