Sorry to hear you feel that way, it sucks feeling down, or as if every day just keeps getting worse and more unbearable.
Currently I am on a similar track, I have been feeling crushed for a good while now, usually it passes after a day or two, it's not lasted this long in a while, I try to cope while it lasts. Though of course coping or distracting yourself isn't helpful if it doesn't pass at all for you, I hope it will pass. But if it doesn't I hope you manage somehow.
If you think it might pass then I suggest maybe trying to do something you enjoy, or something that usually calms you down, maybe a hobby if you have one. I was recently told to go explore a new part of my town by a member here on SASU as a way of dealing with shit a shit mental state and it was actually kind of nice walking around an new area listening to music and just... yeah walking. Maybe that could help you too?
I hope any of this may be useful to you even if only slightly
