How do you feel if I told you that I feel like a freak. I hate myself and what I've turned into?
Are you joking? Why do you think you're a freak?
I took drugs. I've ruined my life.
Plenty of people use drugs so that doesn't make you a freak. Being so hard on yourself will just cause a vicious cycle of viewing yourself in a negative light which will make your mental health worse. You should talk to someone about the way you feel about yourself so they can help you feel better!
I don't want to get therapy.
Most drug addicts don't want to accept the reality, and they tend to feel unworthy, so they don't want help. I think you are a great person and deserve so much better, so you really should go to therapy for the sake of the people that love and care about you.
