I'm in a very similar position, but I have thoughts and tips. Feel free to DM me!

I’m looking for similar help! Right now I just try to use green tea later in the afternoon, and I get up and move around some (stretching/yoga/standing chore) instead of sleeping if it’s not too overwhelming. I know that too much sleep can be unhelpful for depression, but sometimes it’s just what your body needs. Also, you might want to bring up sleep with your doctor. If you’re not getting restful sleep, it doesn’t matter how much sleep you get. You just won’t be able to recoup. I use something for sleep overnight, but only as needed because it tends to make me drowsy in the morning if I take it consistently.

Yes I have crushing fatigue as well, and I have no idea what to do about it

I'm the same way ..I just started celxa a week ago low dose of 10mg at night but wake up still with anxeity and sooooo sleepy
