Thank you for taking the time to write us here at PsychCentral. You have listed your age as 23, and I believe the primary goal should be getting out from your living circumstance as it sounds like it isn’t offering you a place to flourish. I realize this may not be something you can do quickly or immediately, but having the eventual goal to find a place to live that is more conducive to your well-being is important.
While I certainly believe individual or group therapy will be helpful I think there are some self-help books that might give you some skills for coping and growing. Our own Marie Hartwell Walker has a wonderful book, Unlocking The Secrets Of Self Esteem, that I think you will find quite useful. Here is an introductory video about her work.
