I had a lot of trauma in my life as a child, my parebts split up and my mother decided she didnt want me so i went to live with my dad and his wife. I went 16 years without any contact with my mother because 'she didnt wanna know me' but when i turned 16 my fathers wife decided she no longer wanted me around so my father chose his wife over his 2 daughters. Now my biological mother has decided she wants to be involved, i've let her but she keeps letting me down. All of this has completely lowered my self esteem and confidence and i've become very angry, which i unintentionally take out on my boyfriend. What could i do to make me less angry and become a better persob without medication and psychiatrists?
