Depressed

I feel worthless and I hate feeling this way because my baby feels everything I feel. I feel hopeless and alone . I don't know what to do. I lost my job as a result of a legal fight with immigration to recover my legal status in the USA, my fiancé just throw me out of our apartment because he doesn't want to deal with my immigration problem, I'm 17 weeks pregnant and I have been fighting with depression and PTSD since 2012. I feel I lost my life and I can't get it back 💔😭
