How to stay “happy”

Hey guys, I’ve been going through it to be honest. I can go into detail about the journey I’m still on with everything connected to this, but it won’t change anything, and I’m feeling absolutely at the end of my wits, and I’m exhausted. I feel ungreatful because besides my health, I should be happy with everything I’ve got going for me.

Do you have any advice to help with holding onto that feeling, and seeing the positives even though that feels impossible sometimes? Anything or anyone?
