I have SAD, and miserable weather exacerbates my depression. As my luck would have it, I am forced to live in one of the dreariest parts of my country, where summer only lasts six weeks each year. Spring is torture every year with the misery lasting for weeks at a time, from April through July. It's not unheard of to not see the sun for ten days or longer.
All the places that have an ideal climate for me like the southwest, have costs of living that are completely unaffordable and will forever be out of my income range, given my shambles of a work history.
