So stressed out, need to vent(venting rant feel free to comment)

I am Hella stressed out. I'm trying to be this super mom/girlfriend/ daughter. I can't take it anymore. This morning I finally had a mental break down and burst into tears I practically bagged my boyfriend to stay home from work but he couldn't and left me there crying my eyes out. I'm 30 weeks pregnant, a young mom who got pregnant the first year she was meant to go to university full ride scholar ship which I gave up to take care of my baby. I'm so stressed out. When I found out I was pregnant I gave up alot and became this stay at home house mom because my fitness trainer job I had full time let me go when I was 18 weeks pregnant due to the fact that my health was at risk so was baby. So I lost my job, my scholar ship, the university I wanted to go to, I lost a lot. But I love my baby she's the best thing that ever happen to me I wouldn't ever change this for the world. I'm just so stressed out trying to be perfect. I cook, I clean, I do all the errands, I take care of our 3 dogs and 3 cats(which one is sick right now), I clean all the clothes, I wash the bed sheets, I do everything top to bottom. And still my own mother (who we share a house with on weekends when she visits) yells at me and tells me I sit on my ass all day when I don't to the point where my feet are swollen likes balloons, my head hurts from not eating, I had 3 meals maybe that day etc.
