So stressed out I am feeling depressed

I have a 2 year old son, and I am 22 weeks pregnant now. I just found out that my insurance was cancelled for this month because a previous county I lived in failed to terminate their case, and this county wants my baby daddy's proof of income in order to get my insurance back. If I don't turn it in I lose all state not just county, but baby daddy refuses to help me get insurance back by giving me the documents I need. I finally found an ultrasound place that will allow my to have my son with me, because I have no family or friends to help my watch him and his father can't take time off work for various reasons. But now I can't do the ultrasound because I have no insurance, I am planning on moving out of California in a couple weeks, but my OB is stressing about having this ultrasound done before 24 weeks. I am so stressed out I don't know what to do. My whole pregnancy with my son his father and I fought, and I couldn't enjoy my pregnancy. And now I am going through this crap with this pregnancy, he has made it clear he is not happy about this baby. And I am starting to resent being pregnant. What do I do? I feel so alone and angry right now.
