Hey Curry...I'm at a little over six weeks and I am still dealing with intermittent fatigue and also having to face the wreckage of my life sober....I've had some very, very cranky and pity party days because of this. You're not alone.
On the up-side, I've also had some very hopeful and wonderful days directly as a result of being sober! Lots of ups and downs; I think this is very normal.
Dunno what to say about your mother...except I guess whatever she is dealing with is her problem, and you have enough going on with school and cleaning up your act.
I also agree with LaFemme, stop reading symptoms online! All you'll do is scare yourself silly.
