I don't know where to start with this one, I just feel so shockingly unwell and don't know what to do. I have had Covid-19 recently, started a couple of weeks ago when everything tasted/smelled weird and then I had this really low mood (which is not like me) and was snappy with people. I then came down with cough/cold symptoms and for almost a full week I had a raging temperature, couldn't get warm, sweating, delirious, and continuous cough. I have also had symptoms like anxiety, feeling really low and emotional and just really not myself at all. Can't concentrate on my job, can't make myself do work. Over the last couple of days I have now had the most intense nausea and feeling really sick, can't eat. I have never been this unwell. On top of all this, I know it's embarrassing but I have had threadworms, don't know where I got them from, I'm up all night itching and I also have a horrendous yeast infection so down there is extremely sore. I have been taking drops of oregano oil to kills the threadworms as this is the only thing that worked last time I had them. Over the last two days I have had 7 drops (7 yesterday and 7 today). I am now worried that I have overdosed and that is why I feel so sick, I'm worried that you can overdose and it can be fatal so I'm really scared and worried, and I just can't seem to get rid of the threadworms which are driving me insane. I don't feel well enough to do anything or go anywhere and I can't eat as I feel so sick. I was supposed to be going out this evening but just didn't feel well enough and the waves of nausea are making me feel so panicky. I just don't know what to do.
