Tell me about it. I have invested in a new business (anyone want a fully custom PC case? heh), and now I have to stock up on food and seriously consider how to live with long mass blackouts, as well as prepare for mobilization to fight Russian invaders if they succeed in Ukraine. Eh, I'm already suicidal, so that would be a better way to go, I guess.
Hey man, if you're really suicidal, please get help.
Aside from that I can personally recommend exercise, d3, sunlight and a regular bed time.
Know that depression makes everything suck, you wont enjoy things you used to. Even if your life was great you wouldnt enjoy it. But you will again once you get over the chemical imbalances in your brain. I'm rooting for you.
