18 Years Old. Fatigue, brain fog, vision problems, derealization etc. PLEASE READ, NEED ADVICE

I am an 18 year old male, turning 19 in September. I got Covid at the end of January, a mild infection. I have had covid several times but never developed post covid/long covid, it has always gone away after an infection, but not this time. 

Since then I have had extreme fatigue, brain fog, unrefreshing sleep and lately blurred vision and strong derealization and also depression. I DO NOT KNOW WHAT TO DO. It's been six months. I'm relatively young so figure it should be over by now. It is so scary to have such impaired vision. My parents hardly believe me. They think I'm exaggerating, which makes me even more frustrated. I'm too young for this. 

I have also had other slightly minor symptoms such as diarrhea and for about a week in March I had severe numbness in my arms when I woke up after sleeping. I don't know if this was related. But probably because I never had it before. IS IT NORMAL FOR A YOUNG PERSON LIKE ME TO DEVELOP LONG COVID? 

The depression didn't come until about 2 months ago. Before that I was mostly just tired in mind and body. I don’t recognize myself. It's such a strange feeling. Nothing feels real. Everything is like a dream. Feeling out of touch with reality. 

I try to eat as healthy as I can. In the last 1-2 months I have bought the supplements "rhodiola rosea" and also "acetyl-l-carnitine". And also black Seed Oil. I also take omega-3 daily. Rhodiola doesn’t help, that I can say. I am thinking of buying more supplements. 

It's so weird. It feels like there is something disturbing the brain and body that makes me feel tired, stressed, anxious and generally depressed. I would really like an explanation for this. How can my vision be perfectly fine for the first 4 months and then now become completely blurry and out of focus. The virus seems to be moving around in the brain and body. And therefore it is unpredictable to know if you are really getting better. The derealization, the depression and the poor vision were not as strong in the first months. Now it has taken over everyday life. It's so uneven. One day I can feel better and other days I just want to lie in bed and watch movies

As I wrote before, it's scary. From everyone else's point of view, I look normal. But on the inside, I don't feel well. And that makes me sad, because I can't change it. My parents just tell me to start exercising so it "goes away". But they don't understand that hard training makes no difference. The virus does not disappear just because you "train hard". However, I think it is important to move in some way on a daily basis. 

I live in Sweden and graduated high school 1 week ago. Luckily, I can now get more sleep because it's summer and I don't work that much. The last months of school were tough. I had a really hard time listening to the lessons, but I needed to do what was required

I have to say though, I'm grateful and feel better reading everyone's stories on reddit. It makes me feel less alone. The reddit stories are currently saving my mood haha :)

IS THERE ANYONE UNDER THE AGE OF 20 IN THIS COMMUNITY? I will post this on other “longcovid-communities” for extra advice. 

I appreciate any tips I can get. It can be food, supplements, fasting or something else.

The most annoying thing about all this is that NO ONE understands me. If my parents don't believe me, how will my friends, the doctors or anyone else believe me? No one believes that an 18-year-old can develop long covid. Will I live my whole life like this?

They say “You are too young for this, you will get back soon”. What if I don’t? I very much doubt it right now. 

I know I am only 6 months in but I am starting to lose my mind. I feel lost, no support from anyone.
