That's really tough! I'm sure the nasty weather we've been getting really isn't doing your psyche many favors. As much as it would stink to have more pills added to your regimen, is it possible to seek out Adderall as a temporary fix? It could help offset the sleepiness of your other meds, though I don't know if your doctor would disagree. I had a prescription for it to get through grad school because I had similar issues with my meds (though my diagnosis is PTSD). What helped me get through classes was setting very small goals because my problem came from feeling overwhelmed with the amount of stuff that had to get done.
