Update
It seems I wandered away from BL for a while and forgot about this thread. Let's just say that a lot has happened in the meantime. I figure an update is in order.
I'm still on the same doses of lamotrigine, aripiprazole, etc. as before. The only real change has been the mirtazapine.
I'm at 45 mg / night of mirtazapine, and it's worked wonders. I used to have lots of bad intrusive thoughts; the mirtazapine eliminated those. For example, I'd be sitting in my room, listening to some guys cutting the grass outside. My thought process would go as: that sound is loud and annoying, there are guys outside cutting the grass, if they're doing that they must have jobs, I have no job at the moment, I must be worthless, the world would be better off without me... That kind of thing. But those thoughts are fading memories now.
Mirtazapine also helped with the depression quite a bit, but over the last few months, I've slid back down. Not nearly as bad as before (no suicidal ideation or anything), but definitely in a slump. I don't know where to go from here. If you happen to want a taste of what my baseline has been for the last year or so, see
this thread.
I can't say much about weight gain due to some physiological issues, but I think I'm slowly gaining some fat around my stomach.
As for therapy: I've been seeing various therapists all along, but I think I have reached the limit of what psychotherapy can do for me. At this point, it feels like I'm listening to a motivational speaker talking to a brick wall.
Finally, alcohol: I could write a book about this. The less said, the better. I really should have heeded R(x)AGE's advice to stay the hell away, but it's a little late for that now.
In conclusion, mirtazapine really helped, but not quite enough. Thank you all for your help in my time of need.
