Cutting and pasting from another thread, which I don't normally like to do, you deserve a personal reply twyleskyles but only wrote it this morning and advice stands here just as well:
What do you like to do, or what do you think you'd like to do? There will almost certainly be a social activity to be made from it in some way. Start looking. I took up climbing at an indoor wall. They had a 'partners in climb' thing weds nights for people like me who didn't have anyone to go with. Good exercise for one, none better for lazy exercisers like me, loads of fun, been wanting to take up the climbing for ages and here was a social opportunity to be had from it. Wins all round. My local addiction unit has a social thing for recent ex-addicts needing to fill time with activities with others like themselves away from their circle of still-using friends. See what your local units can offer. There may be something similar running near you? They may also have a need for mentors on a voluntary basis. Put your experiences to positive use with others in a similar boat. That could be very valuable for you going forward yourself ( though perhaps a little more distance is needed just yet for that )?
