I had to change the people I associated with...that was the way I got around it.
I totally forgotten that there were people who didn't drink themselves into the ground, or who needed to be high to go out.
You have to put yourself out there tho - volunteering was a good way to do that for me - I met a lot of new people and got used to being around people again.
Exploring hobbies - old ones and new ones - was good too - I made a few good friendships that way
