Im in a similar situation, you arent alone with this, even if that's sometimes what it feels like. It's just the depression making you feel that way i guess. Im sure you'll be fine again one day, dont give up!
I've had that sleep problem as well, i had so many nightmares, always the similar **** so i didnt even want to sleep anymore, i was and still am sometimes even scared to sleep..
I already tried moving my bed to another room and stuff like this but the nightmares still come sometimes and because of the depression you're tired all day anyway.
What helped me a little was go to bed at the same time each day, find your rhythme.
Also,i know sometimes its tempting to sleep during the day, sleep and forget the bad feelings for a while,but i think it makes it worse sometimes. You wontbe tired enough at night to sleep without waking up, try to sleep 7-8 hours at night, i hope it will help a little hugs tightly
