Covid 19??

I just tested positive for covid, I have been sick for about a month know, I have two baby's one is almost 2 and the other is 6 months. I am terrified right know and have been crying because I'm scared my baby's are going to get sick because of me, I'm a single mom so I can't quarantine and leave them, my son was tested yesterday and he was negative and they refused to test her , doctor said no use of me wearing my mask because I don't exposed them if they get it they get it basically.

We have so many people here dying and stuff I'm so terrified of loosing my baby's , my symptoms are

Nausea, diarrhea, chills, fever, shortness of breath body aches, bad cough and stuffed/running nose. Advice or how did u handle it, I feel so bad because there driving me insane also it's been nothing but crying, tantrums and idk how I'm going to handle it for two weeks not sleeping
