I, too, deal with depression by sleeping. If I don’t have anything to do during the day (like if I take the day off from work bc I’m too depressed to go in) I will sleep for six to eight hours during the day, get up to pick up my son, and go back to sleep at 8pm and sleep straight through until I have to get up again.
Like others have said, sometimes it’s better for me to be asleep because at least then I’m not actively planning anything.
