Are you on any medications for your depression? Or is part of the problem that you can't afford to get help? You do sound deeply depressed.

Yes, the pandemic is limiting and many are suffering. Are you able to go for walks, cook meals, etc. Do you try to help around the house? Could you do the shopping (perhaps your mom could pay but you go or you could go together) just to get out of the house? Sorry things have been so sad for you Gasplessly.
