With a name like Fungal, I can see why your family wants to avoid you. At this time, their shunning of you might be a blessing.

You don't live with them. This is just them appropriately social distancing, it sucks for you but it's to keep everyone safer.

OP, I've got a spare bedroom for you here in the Upper Midwest of the US! :-D

OP your family is just exercising an abundance of caution. I know it is probably really hurting your feelings, but if you have been going out, going to work, etc, it is possible you are a carrier who isn’t showing symptoms yet and you could get your whole family sick. That would probably make you feel much worse lol. My suggestion: wait the two week recommended quarantine period and if you show no symptoms then, ask again. Actually ask in advance so you are all on the same page. Then they may let you in. And strap in. This is going to last a loooong time. Certain powers that be are trying to lift the quarantines before Easter, but we will just see a spike in cases then and go back to quarantine. So buckle in and hunker down and try not to let this family thing make you feel bad. They are really just trying to be careful and safe for everyone.
