Trust me Fatcat. This is momentary. You will feel better soon.
I have to agree with close. Basically you will have the moment when you just are fed up, and willing to do anything to quit. I know it sounds cliched but mine happened in jail. I was sick, sitting in a cell, and I realized that I have been trying things my way for so long, and maybe it was time to try someone else's way. I had been to rehab before, but I held onto a lot of bitterness and resentment which always led me back to using. I tried detoxing at home many times and I never made it. I was/am a chronic relapser. I had to accept that, and accept that I am going to be uncomfortable for a good amount of time. I ended up getting bailed out, and my bondswoman was extremely compassionate. She gave me the option of being bonded out and going to rehab, or staying in jail. I chose rehab. The difference this time was that I was ready to stop. I was willing to do what others suggested, no matter how mundane, or painful.
The biggest thing for you right now is to decide what you want to do. You know you have a problem, you know you need help. Maybe a stint in rehab might help you. Not only will you get away from all your triggers, but if you let them, they will help you with any mental issues you may have (which tend to be one of the problems for the self medicating addict, which most of us are.) Just know that we are all here for you. Be kind to yourself and take it easy.
