Warm face, tiredness -_-

[professor]

3 days ago, I started feeling my face quite warm, and I'm really tired, kind of "sleepy", or a bit "groggy" during all the day. It really made me panic, as I now suspect I have covid, although these (warm face and tiredness) are the only symptoms. I've been treating anxiety for 10 years, currently on Mirtazapine 15mg, although I haven't been taking it for +- 3 weeks (logistical problems related to buying it).

The thermometer does not indicate fever. It's always around 36 - 36.5 °C. But why I feel my face so warm, and feel so tired? Can it be the anxiety? If so, besides taking my med (which I will buy tomorrow), what else could I do to fight this thing? I don't want to be at my bed all day feeling sick. I don't want to be sick. I think I'm not sick, but keep being afraid of being sick, having Covid etc, taking my temperature all the time... I need to stop this craziness.

About taking temperature, I have a digital thermometer and take my axillary temperature. I read somewhere that after the thermometer beeps (telling me I can check the temperature), I still have to wait around 3min to get the correct temperature. Is this true? Because if wait, it keeps going up to about 0.5 °C from when I hear the beep.

Sorry if all this sounds so... stupid. When I read it, I really feel stupid. But I don't know what to do, how not to worry, or if I should worry. I just want all this to end. Living alone and being in quarantine for 6 months does not help. I'm alone, working and studying from home, and very rarely meet someone, always with a mask, some distance etc.

Professor,

First of all you need to keep logic in to the scenario.
If you live alone and don't socialise, it's highly unlikely that you will catch anything anyway.
The warm face could well be due to anxiety or even humidity. I get a warm face quite often.
The tiredness could also be anxiety related.
If you are over anxious, your body pumps adrenalin which can leave you feeling drained.
Is there really a need to take your temperature constantly or even at all? I'm sure this is feeding your anxiety.
Maybe take a break from it.
