Hi, I'm in UK. The self help groups are helpful in part but very limited in what they can achieve as the range of symptoms is extremely wide and random and each person is different. I think though that it's really important that a clinical diagnosis is made to ensure that it definitely is long Covid/ME/CFS before any real support is taken up as it actually could be a whole range of other things rather than these. It took many months of tests by gp and at hospital to eliminate various other illnesses before my diagnosis was confirmed by a Consultant. I think it was early 2020 when the first covid cases were discovered in the UK and so although his symptoms are similar to long covid, it might be that he has ME or CFS or something else altogether. I'm not on any prescription medication but do take magnesium citrate which helps a bit with the ongoing insomnia and my brain fog is almost daily along with the actual fatigue itself, and sore joints. There is a lot of terrible stuff written on the internet, but there is a site that I can't remember the name of right now that is ME/ CFS based that is recommended by my gp which is helpful, and although I haven't used it Chest Heart and Stroke charity offer some online help but I think because of volume may only be able to support cases of diagnosed long covid but it's worth while contacting them to ask what support they could offer you. It is awful, and really hard to organise your life around as the symptoms seem to arise randomly and can be so varied.
