get out in nature, walk. unplug, meditate often. past is past, it's gone. just in front, that's what reliable. you get to craft and curate it.

I reached the point where I can’t afford any stress

this thou, this is gold. remember this. keep repeating that, over and over until you find what the input is feeding it. slow cook it away like chicken from the bone. you'll feel a million percent better.
