I posted about a week ago talking about how I was a crappy parent, but good news! My old therapist agreed to start seeing me again, and I've been practicing my DBT skills by myself. 

Yesterday I had a confrontation with my MIL over her undermining my parenting that went very well, considering my disorder. I didn't freak, and she didn't go around causing drama, and that was the best scenario that could have come out of it.

I've fully thrown myself into being a mom full-time again instead of letting my emotions get out of control. My son gave me four hours of sleep last night, so I am very exhausted, and yet I was able to monitor and control how I was feeling when my son had a tantrum and also when a classmate said something very insulting about people who have kids in their early twenties (like me). 

My fiance's on board with my therapy and has told me he has complete confidence in me learning how to manage myself. I know it's a long haul that I will have to deal with this the rest of my life, but I feel like there's hope.
