((Rennips)) - I agree with the above - you are NOT a loser, you are here asking for help. Though crack was my DOC (drug of choice), I went through a long period of abusing the he!! out of opiates before that. I, too, shot up. For me, I was addicted to the ritual of using the needle almost as much as the opiates.
That being said, I did quit. I don't know WHY, but I didn't go through withdrawals, just quit (lost access..long story). It took a while before seeing someone injecting insulin didn't throw my brain for a loop....the damned needle.
SR has been a HUGE part of my recovery, but I also agree you may want to check into rehab.
Hugs and prayers,
Amy
