Celeste might be a good choice, though the end of the game (after the "Rock Bottom" section) is quite uplifting, at least until you reach Chapter 9.
I'd mention The Cat Lady (which I haven't played), but that might not be a good idea if you're in a bad place mentally. (The game in question, and I believe its sequels, really do need some content/trigger warnings for serious dark topics like depression and suicide.)
Anything with SAD music
SAD music is = whiny music or emotional music in E#
Isn't E# the same as F?
(I don't see F major being a good key for this, Maybe F minor would be better?)
