Forgive yourself. Get away from your triggers. Exchange your bad habits for good habits. Like if you get horny put on your shoes and go for a walk or drop and do pushups. Finding friends is easiest if you start a hobby. Say you like guns. Become the member of a gun club. Then when someone who has a gun you like shows up. Talk to them about their gun. See where shit goes just avoid coming off as needy and desperate.

Recovery is not a one stop shop for most people. Understand that you will likely relapse. If you do try to avoid the fuck it all response ;)
