I’ll just add that I moved from Oregon to central NY and found the latter much more enjoyable during the winter. Much less grey skies and those cold sunny days were refreshing. I lived in Ithaca and not Syracuse so the lake effect was not so dominate. To say what may be depressing in the winter is difficult to answer. If you’re at all worried about it, simply eliminate those schools you feel may make things worse. Life is interesting and surprising and that’s why it’s worth living. Most schools are sensitive to depression and have good resources. Good luck.
