I feel like everyone should just give up on me
Why do you think everyone should give up on you?
People keep calling me a piece of shit.
You should go to therapy if you have these negative thoughts all the time. This could be a sign of depression.
Therapy doesn't help with mental health issues if I have them. I feel like no one will understand me.
I am sorry people call you bad things, you don't deserve that. If you feel insecure you can change therapists and find someone you feel more comfortable with.
