CW for covid in case anyone needs

Not doing too great right now. My main worries are if I caught covid, and all the uncertainty that comes with that. How bad will it be? How will I manage? Will I have long covid? Will the other person I’m living with catch it? What do I do? Will I survive? Will it be painful? It’s a lot and it overwhelming me right now and I’m not sure whether this is an anxiety headache or a covid headache or both. 

Does anyone have any tips to deal with this? I am usually alone because the other person I live with is at work most days. I drink water, I try to eat enough in a day, I still get up and walk around most days, I rest and sleep plenty, and I can rationalize most of my anxiety. What else can I do, to feel better? To cope with the exhaustion? The constant worry? The uncertainty? Especially the uncertainty. 

Thanks in advance for any help.
