hey, YM20 - your instict is correct. while masturbation is very good at relieving stress, it's not healthy if that's all you do all day. it sounds like you need professional treatment for PTSD and depression. are you seeing a therapist? another option is going to Sexual Compulsives Anonymous 12-step meetings. there you will meet others who have similar problems - pornography and masturbation addictions - and a program that works to help you have a true life. you will also make friends there. here's a link for you: http://www.sca-recovery.org/
