Oh, I think I would say not dating more casually when I was younger. I stayed in one unhealthy relationship for way too long and then after that I kept trying to meet “the one” and it was pretty counterproductive and I think it actually made me a worse partner to the people I dated.
I really wish I would have done therapy sooner as well. It is expensive so I definitely couldn’t have afforded it for most of my life. But I might have been able to start it sooner
