Hi friend,
I'm so sorry you feel this way. But I can say, I get a very similar feeling, especially at night time before I go to bed. It feels like the weight of the world is wrapped around me suffocating me and all I can do is curl up in bed and try to cope. You may or may not believe in spiritual warfare, but personally, that's what I'm pretty sure this is, for me at least. And for me, praying always helps even if I don't feel like I have the strength or words to pray.
My friend, know that you are not alone. I wish you all the best.
Keep fighting.
