Mother/ daughter relationship

I'm not sure if this a right place to post this but I'm really struggling in my relationship with my mother. I am 32-year-old female and my parents got divorced after I lost my brother to suici** when I was 17. After that I really had a hard life and at the age of 22 I took the responsibility of taking care of my mother financially. Long story short I got married few years later and moved to another country and brought my mom to my new home after 2 years. When she came our relationship was not great as she was all over me for that I changed and I didn't love her any more etc. Also she being home all day every day was driving me crazy as I needed some peace and alone time with my husband. She went back and came back a year ago with a plan to stay forever. We had a talk and planned her to move out and get a place for herself but she doesn't have money, and I can't pay for anothe rent untill she get her residency. Now I'm having some problems with my husband and am in therapy as I'm considering a divorce and am in a very bad mental stage. Meanwhile today I had a very big fight with her because I went out with my girlfriend and didn't tell her my plan in advance!! Yeah because of this. She started saying yeah buy me a ticket and send me back you don't respect me and don't treat me well and to the point I lost my control and started hitting myself. Now she is not talking to me, locked herself in her bedroom waiting for me to go and apologize. I'm really tired of this. I'm thinking of sending her back to our home country but I feel bad for leaving her alone. What should I do?
