I have cut myself and regret it
Why did you choose to cut yourself? Are you experiencing anger about something?
I do not handle my anger and hurt very well
Cutting yourself is a serious mental disorder and you need to seek immediate medical help. Call a hospital to get a recommendation for a Psychiatrist or things will continue to get worse.
Fuck the hospital. I hate that place. I'll take care of it myself.
If you have tried to get help in the past and it hasn't worked, maybe you need to find a new therapist. Cutting is a serious issue and it's unlikely you will be able to quit all on your own.
