In between jobs again recently and as usual everytime this happens my stepdad rips into me every chance he gets about having "no money and no job"
Among other things like calling me a parasite or whatever.
Go into mental health treatment soon and that cant come soon enough to get away from this crap.
People project their fears and themselves onto others. Also, sounds like there's some unhealthy competition for your mom's attention.
I'd try to bring that calmly to her attention too, and have open lines of communication with her. Maybe mental abuse doesn't only go towards you, it's important that you support each other there I think.
Good luck!
