Ugh can life get any worst

Ok guys I’m 30 weeks and 3 days pregnant high risk with boy girl twins I also have an 11 year old girl. My older daughter stayed home from school with a sore throat, congestion and diarrhea she is fully vaccinated for covid and just got her flu shot on Monday and I couldn’t get her in to her doctors until tomorrow morning . I am not vaccinated at all for covid I made an appointment for next week to get my first dose but I am terrified if she has covid I am the only one who can take care of her and I have no family or friends to help me out. I seriously don’t know what to do I’m wearing my mask but she needs me by her side 24/7 right now I’m keeping my distance but still near if she needs me
