You're only 8 days in. Your brain is going to be on a rollercoaster for the next 6 months at least while your neurotransmitters try to regain equilibrium. Yeah life does suck sometimes. I had a rough week with about $2k in unexpected car repair expenses and rental cars. There goes that Caribbean vacation I was planning in September. Life just blows sometime. But it blows less not drinking myself into the hospital, not going thru the motions at another rehab, not getting arrested et. al. I was pretty lucky in that about five months sober, I moved into my own condo after living for a year in a shitbox garage apartment which I wasn't even in half the time because it was so depressing I'd rather hang out with homeless guys drinking tall boys out of paper bags behind the Indian-owned convenience store in my old neighborhood. As my ex girlfriend said, "I was homeless with a home." Anyway, at the time I got sober, I had no idea that my life was going to improve to the point where I'd be a homeowner again in the near future, but I figured that it was not going to get better as long as I abused alcohol and drugs.
Anyway, I made this post not to be preachy but because I saw a post you made in sober living about your high hopes for your Vivitrol shot. Once you get on the other side of six months, being sober just kind of becomes the natural order of things.
