Really just looking for advice

So I am 12 weeks and 3 days pregnant with baby number 3 I’ve lost about 17 pounds sense I first got pregnant 🤰 but in the last 2 weeks . I lost 8 pounds so they addmited me to the hospital per doctor orders . So my family has been so unsupportive my moms is like you have been pregnant 2 other times how the hell do you not control this are you dumb of stupid there upset because I won’t be home for my son birthday I feel so horrible I know but I have to feel healthy to be at home . And be a mother to my children my mom is saying I’m being very dramatic . My sister is being as bad as my mother . I expected them to be supportive and really haven’t got any support from them my mom is leaving on vacation on Tuesday so she really honestly doesn’t give a shit ! I genuinely think I’m alone and they want me to be super women there is only so much I can put on my plate . My dr honestly thinks it’s best I’m here until I can stop throwing up and loosing weight . I’m so fustrated ..

FYI MY 2 KIDS ARE SAFE AND WITH MY FIANCÉ I DID NOT FEEL THE NEED TO DISCLOSE THAT !
