I think that's what it's called?

I easily get down on myself, berate myself, or feel bad whether it's about job performance or the very fact of having so much anxiety, or other things. I know it really hinders me (and I know I should get myself a therapist!), but I was wondering what kinds of things you tell yourself that make you feel better if and when you get like this. I know how I feel is exaggerated sometimes, not 100% 'true' and yet...

So what helps you? What do you say to yourself, what mantras do you have, etc.? I try "I'm doing the best I can" and find it somewhat to moderately helpful... I'd love more ideas!
