Do I know how you feel! It has been awhile, but when I was at the worst of my addiction, I self isolated so I could use and "enjoy" the effects of it. Bad thing was since the high doesn't really last all that long, there was a lot of time to feel depressed and down and sorry for myself. Isolation is one of the worst things you can do if you are an addict. In recovery I have learned that being with people, even if I don't want to be is really better in the long run.
Fortunately, the thought of isolating doesn't happen all that much, usually when I am in a stressful situation. That is why meetings are so important, and I have 2 small groups through my church that I go to weekly. I can usually get out of the funk I am in with those people.
Is anything going on in your life would make this something that could trigger you into using?
