My first thing was to suggest what you're already doing for the psych issues. I've been doing that now for most of my life, and I know how there are always ups and downs with treatment, so just hang in with the program so to speak.
As for the cigarettes. IMO, with all the other stuff you've got going on now is not the time to try to quit. You really are best suited to succeed with that when you are coming at it from a place of strength. Or as was my case the second time I quit, lack of money and just coming to be disgusted by the cigarettes over time.
It was a long process of having them when the money was there, doing without when it wasn't, and over time just developing a distaste for the cigarettes. The first time I did it 13 or so years earlier was from a place of strength though. And had I not decided to try to have the occasional cigar and allowed that to creep up on me I never would have been back on cigarettes. So, you can do it, but if it's not the right time for you it just isn't going to work anyway. It just seems to me you've got too much other stuff going on right now.
BTW, chantix can cause depression--even suicidal depression. If that's what you're trying I strongly suggest you discuss getting off it with your doc! I had the help of Wellbutrin my second time around. Not only is it an anti-depressant, but it does help curb the desire for tobacco!

As for the money/job and grades, I think I would do one spell to help you find a job. (Use the forum's search option. I'm sure you'll find one already posted.) And some other sort of spell for aiding your studying for the grades. (There may or may not be one of those already posted.)
I'd also like to draw attention to the fact that we are only to post spells on one particular board in this forum, and this is not it. So anyone coming in here with a specific spell to help I suggest you post it on the appropriate board and redirect the OP to that post.
