Very sluggish lately

Its been going on for about 3 days. A very mild sore throat and very mild nasal congestion. Both of which are probably a 2 on a scale of 1 to 10. I thought I was getting a cold or something, but it hasn't really been progressing into a full blown cold. The worst part is I've been very sluggish. I don't have the energy to do anything. I mean, I still do it. I haven't missed work or anything like that. But just everything I do feels like such a chore. I feel like I weigh a billion pounds. I don't know if its some sort of new anxiety or maybe its a form of depression? Last week was insanely chaotic for me and I drove over 2,000 miles for work. Yes 2 thousand. So maybe I am just worn out from that? I don't know. I just don't like it. I have this like weirdly mild cold and I wish it would do something. Even if it got worse, atleast I would know it was progressing and I was working towards getting over it. But nothing has changed in 3-4 days.

I mean, anything is possible. It seems kind of unlikely because I pretty much just drive for work and spend 99% of my time either home or in my personal vehicle and when I do drop offs I have my mask and only come into contact with one person who is also wearing a mask. I kinda think if it was covid it would have progressed or I would have a fever or be showing some other sort of symptoms by now. Mainly all I really have is fatigue. The sore throat and fact that I have to blow my nose once every couple hours hardly even seems worth mentioning. My mind went more towards something like cancer, but seems unlikely to be that either.
