Shouldn't have worried about not being able to look after the thread properly, you're all doing a fantastic job! 
I had one of my worst days for ages and it made me very gloomy. The fatigue was all over my face and body, in fact the first thing my best friend said when he saw me (at a distance!) was "You look so tired" and I just said "Yeh, I cannot get over this virus."
I had gone out for a walk round the block and it was so depressing. When I sat on a bench in the sunshine in our local park before coming home I was too sore to stay there after ten minutes. As I walked back there were people passing me and I thought "I bet they think I've lost someone to COVID" because my face was tripping me. Truth is, I've lost myself to this virus for the time being. That's how it felt yesterday. From waking up in the morning and remembering that my teeth had been chattering and then really grinding in my sleep, to my legs feeling knackered and getting the shivers when the temperature indoors was 22 - not to mention the back pain and sore eyes and teeth and even my big toe!! I'm so over this. Except I'm not, of course 
Just looked at the diary and today is day 93 for me. I started with nausea, headache and sore throat on 22nd Feb, and the post-viral agony in ribs and back kicked in on March 17th. I'm a different person now, that's how I feel after this weekend. It has taken all my inner resources to get this far with dwindling optimism, and yesterday I ran out. But I think it's complex and I can't help suspecting that the virus hits us at a very individual level, almost as though it targets our weak spots. That's how mine has been anyway, and although I'm heartened by the thought that recovery is likely (eventually), right now I want it all to just stop.
I came across a book recently called 'The Inflamed Mind' (recommended by a dear friend). It's written by a consultant psychiatrist whose very articulate and convincing theory is that inflammation in the body which produces cytokines passes through the blood-brain barrier and affects the brain in such a way that it triggers depressed mood and thought processes. At least I think that's what he's saying so far, I'm only a chapter in. On our previous thread I mentioned that I've been taking Sertraline since last summer following a particularly difficult period of depression. I noticed within days of starting that I had costochondritis in my chest and intercostal muscles. Basically, I concluded, the medication was causing inflammation as a side effect but I was too desperate to come off it and decided to put up with it. By the end of the year it had stopped bothering me so much but was still there. Then back in March I got this far more intense inflammation in my thoracic spine area and the rib muscles there, which then crept round to my front ribs and sternum for a while. I realised eventually (thanks to some of you) that I was post-viral, but it has been the single biggest symptom for me and I've been despairing of ever recovering after two and a half months of it.
And now my point! I've been so depressed, despite the medication, this last two months. If the inflammation is causing that (as per the professor's theory) then the medication is pointless against it. But, it's also very possible that the medication was causing inflammation last year that made my depression worse than it was before I took the tablets, and in fact the SSRI has actually been working against me recovering from depression by causing inflammation that worsens my mental health 
. In which case, heavy post-viral inflammation added to that is making things much harder, physically and mentally, and in the end what's the point in my taking a drug every day that is worse than useless?! Not only that, but my kidneys and liver have to process that drug and I need them to be as functional as possible while I'm fighting post-viral illness.
The mind boggles 
. Anyway, as of today I'm stopping the Sertraline. I just feel it's not helping me and I'd be better off taking other medicines in the short term that will help with any discontinuation symptoms and possibly also reduce the inflammation, eg. ibuprofen or a prescription of Prednisone.
I just wanted to share that with you, not recommending it by any means, but different people will find different ways through this nightmare and it's a path I'm now willing to take. I've discontinued antidepressants before and got through it without too much trouble, so I'm not particularly worried about that side of things. I just feel I have to try it at this point because I can't bear the thought that I'm suffering more than I need to be as a result of taking medicine! I need to know, and I'll keep you posted
