I've been in the same situation, parents, police and all. Realize that you will not bounce back in a day, it happened to me 10 months ago, and I still haven't got back in the groove. And your friends, they may not be friends now, but they are right, get over the emotional state of it, and fix your problem. It's okay to ask your parents or others for help, just don't have them do it for you. As for the group things and church don't go, because alot of people can go to those meetings and fake everything as I did. You can still go, but it's a bit depressing when you see a faker, or someone crash when they've gone so far.

As the others stated, take time for yourself, for me, I shut all the doors, turned off all the lights, and just punched walled and yelled. It was the only way for me to release it all, wether it's crying or just sitting there, clear your mind, and analyze the situation for what it's worth. It's not rock bottom, because you'll meet it again. It always feels like rock bottom, until you find that you can go lower, but you never picture yourself there.

Good luck, and get it right. Just quit piting yourself and get back on your feet.
