I think the only way I can stop my feelings of detachment from the world is to self harm
Why do you feel the need to self harm?
I feel very stifled and depressed and I believe I need to do something extreme and violent to release myself from this suffocation
Have you tried talking to someone about how you feel. Therapy could be very helpful to aide you in navigating through your feelings.
Therapy is a load of shit. I don't need a therapist to tell me who I am.
They are not there to tell you who you are, I promise. They are just there to help figure out the underlying feelings, you should try it! Who knows, this could be just the solution that you need.
