middle, after reading your story the only thing i can say is:
Have you ever considered working with kids at risk? if anyone had a reason or excuse to turn to drugs etc. it is someone who had a childhood like yours. but YOU didn’t! you rose above and faced your challenges head on! i think there are many kids out there you can help because you went through either the same challenges or similar ones as they have. you can probably understand them and where they are coming from better than most, and those kids will probably listen to you more than to a rabbi or someone who they feel has no idea what its like to be them.
one more thing – be proud of who you are!
