Mental health is weird. Sometimes, when I'm in a bad place, I try a list of phrases on myself to see what resonates, what relieves the bad cycle in my head. In no particular order:
It's not your fault.
I'm not mad at you.
I like you.
I'm not in a rush, and I'll stay until you figure it out.
That makes a lot of sense given (social structural problem or person's behavior).
You still deserve help even if your struggle is not desperate.
Got any yourself?
