I’m toxic

I have admitted for a while that I have toxic traits, I’ve been pretty toxic since I was maybe 12 (I’m 21 now) I have been trying to work on myself, but I’m not sure how to stop being toxic without turning into the pushover I was before I became toxic. When I was little I was everyone’s doormat and I guess I got sick of it and turned into this monster that everyone, especially myself, hates.
