Peace and Blessings David,
Glad you could join us! I can identify with you. Scared, confused, angry and alone...

If you have a chance to go to Rehab, by all means give it a shot. What do you have to lose, except maybe a drug habit? Give yourself a break, try going to some meetings, listen and talk to others who have been where you are and keep coming back. I did...
Peace, your friend in recovery, Shakur
