Another way you can be nicer to yourself is by replacing some of that asshole language that you use toward yourself in your head.

I'm allowed to male mistakesI'm allowed to feel good sometimesAnxiety is my bitchI don't like these feelings, but they won't hurt meI'm going to be alright

You need to set yourself up for success, too. You need to invest in yourself. You need to stop being a butthead and sabotaging yourself.
