I'm going to destroy my life because I can't get laid
Why can't you get laid?
Because of my ugly face and small height
I know you're frustrated but you shouldn't intentionally destroy your life. You should seek some professional help if you're feeling this down.
Screw professional help I'll handle this myself.
Think of how your friends and family will feel when they lose you. You are too concerned with sex at the moment. There is a whole world out there that you can still experience and along the way you might still meet someone who loves you romantically.
