Post covid syndrome. Memory problem!

Hello Doctor, I have been suffering from post Covid syndrome for the past 1.5 years. The most disabling symptom is severe Fatigue: it feels like my body does not produce or regulate enough energy to get through the day, making it impossible to work or live normally. My second major problem is what feels like autonomic nervous system dysfunction. I have difficulty processing sensory stimuli and my body doest seem to regulate itself normally. For the past 5 weeks, i have had a subtle feeling that although i can see normally but my brain isn't processing visuals information correctly it's difficult to describe but it feels like a disconnect between seeing and processing. I have gut related symptom also despite working on my gut health for past 9-12 month, I still Occasionally develop a swollen abdomen that doest feel like typical bloating - it feels like nerves controlling my gut aren't functioning properly. This was constant early but is now intermittent. I also have memory problem
