Covid 19

My baby sister had symptoms of covid this past week but didn't let anyone know until today when she tested positive exposing my 2 month old daughter. No she didn't hold her or get too close. I'm very pissed off that she just didn't stay home & choose to exposed not only me but my several family members including another family members child whom is younger than my daughter. I'm going in the morning to get tested & calling her Dr asap to see what I need to do to keep her safe just in case I'm positive. I've cried about this bcuz I've been so careful. Now I'm on full mommy mode locked in my room mask on & disinfecting everything washing all the laundry tomorrow. Every possible scenario has went through my head I'm not gonna get any sleep tonight. Ugh
