The sun came out today, I felt ok for a while and even enjoyed something.
Possible trigger:
I'm terrified it won't last. It hasn't lasted in the past 2 years and the black abyss is waiting to swallow me up again.

I try not to think like that and make a self fulfilling prophecy.
I had better go and 'enjoy' the rest of this day while I still have it. Thank you all
