Sick or no?

So recently it’s been cold here in Florida and this morning I woke up with a dry throat and a bit of liquid coming out my nose. It’s not enough to be sick sick. I’m worried because my family had people over for thanksgiving (I had no control over this situation because my moms the head of the house so don’t blame me for not following safety covid protocols) if it were my choice I wouldn’t have anyone over. And I’m just worried if it could be covid or if this is normal to feel when it’s cold outside or if it’s a normal cold. The cold tends to affect me since it’s always hot here in Florida and my body is sensitive to temperature changes. For example if it’s too hot I get a bit dizzy. I’m just asking because I have anxiety and I’m nervous today.
