I’m just gonna share what I did when I was at that point , ( and I’ve been there more than once ).
I started watching YouTube a lot and learned a great deal. I didn’t have the strength to read a whole
book so I watched videos on this very subject. I listened to what the great philosophers had to say about
this subject. and psychologists and just regular people. I immersed myself into the existential question
of “ Why “? It got me out of myself and “ into the moment” , ( which I believe is the secret to carrying on ).
There is such SO MUCH to learn. Hoping you pull through…..
