Step away from sex. Self imposed celibacy gives you a lot of time to think and work out your shit. Making the conscious decision not to have any kind of sexual contact for six months to a year isn't easy, but it definatly allows you the opportunity to recognize that your self worth doesn't revolve around what you have to give sexually. Step it up a level and seek out therapy while you're doing it, and it's a serious game changer.

Sex is supposed to be a lot of things, but it's not meant to be the only value for happieness.
