Here's hope! After I was free, that upbringing turned me into an amazing adult. I knew what not to do. I witnessed every shitty trap and mind game and red flag. I played that game, and survived it. I can spot that shit a mile away in other adults now too and know who to avoid. I can catch myself almost immediately if I ever do something similar and things have been so good. My kids will never have to deal with because I can look back at the changes I wished for and just make them happen myself.

Things that helped while I was stuck. Have a savings of your own so you can support yourself. Have a license so you can leave and come back as you please. Have a good plan. Not just 'school in 2 years', but a full on 10 year set of goals that make it so you will never have to live there again. I worked part time while I was a full time student and it made that plan possible. I planned for stuff that might come up which would make me need to move back home and avoided it. What if I couldn't find a room mate and had to pay all the rent alone? What if I got evicted? What if my crappy car stopped working? So many backups plans. So many secret savings stashes. My jobs through school kept me safe.
