Help! Im so confused. (Longish)

So my whole family left. I'm 13 weeks pregnant and struggling as this pregnancy is a very hard/draining as iv had past miscarriages. So what does my family do? Leave. My parents went on a cruise leaving me with my Autistic nephew whose 4 whom they adopted, my own son whose 1 and a half and 3 teenage boys whom they foster. All children (including myself) have appointments and other crazy schedules. My husband left the state for work and instead of checking on me and the kids he completely ignores me to hang out with new friends and go spend money we dont have. Im drained emotionally and physically and all I want to do is cry. What do I do?! I feel ridiculous for being angry at everyone but at the same time I feel justified. Am I being stupid?
