Pink Cloud is bursting a bit

I've been on such a spiritual and emotional high that's just been building since I got into AA.  I feel myself slipping off of it a bit and it's scary.  Doubts are creeping into my mind and thinking about the relationship of mine that just ended.  Missing having him in my life...sexually and otherwise.  Feelings of insecurity, uselessness, hopelessness, and worry are setting in and my anxiety attacks are back.  I'm so lonely but at least I got my meetings.  I just wish I was where I want to be in life and wish I could accomplish more things in a day than I'm able to right now.  It's overwhelming and I'm depressed.  I didn't think the first stages of sobriety would feel more like manic depression!  Feels like I'm losing my mind.  But maybe I need to lose it in order to find it, eh?
