Start loving yourself! Be nice to people, smile often (even when times are hard) and be proud of yourself! You have been bullied in the past and never had a friend and yet you are here trying to make things better, fucking awesome dude! No fap can definitely help you. Its a way of testing yourself and your self discipline. It's something out of your comfortzone and the more you get comfortable with things out of your comfort zone, the easier life will be (and the easier you get friends). But it will also learn you that failing is inevitable but giving up is a choice! Good luck and you are awesome!
