Had almost non-existent anxiety when I was on 15mg, but I had a pretty massive weight gain due to a huge appetite which I attributed to the higher dose. Had to lose weight as I had really bad cholesterol levels. My psychiatrist decided it's time to start waning me off slowly, and reduced it to 10mg a month ago. Since then, I've had my midterms and I've been pretty jittery and anxious, which is making it really tough to study and function in general. Had an attack a couple days ago and had to resort to my SOS med. Am also on Vyvanse, and the anxiety really ruins my study sessions when I just overthink and don't get anything done. 

What can I do? I'm afraid of going back on 15mg and repeating the weeks of drowsiness and nightmares, in addition to the increased appetite. At the same time, my social life and grades are also immensely important, and the irrational fears may cripple it. Winter is making it way worse as well, had very similar mood changes and attacks last year. Are there other ways of dealing with anxiety? (maybe increasing the frequency/duration of my therapy sessions?)
