Welcome, @sahilbhaia03. I moved your post to this related discussion about chronic fatigue syndrome so you can connect with others members talking about CFS. I know how debilitating chronic fatigue can be. You've been dealing with this for such a long time since a young age.
I'm not aware of specialists in India. Should you wish to inquire about treatment at Mayo Clinic, here is the contact information: http://mayocl.in/1mtmR63

One silver lining of the pandemic is that CFS is getting renewed attention by health care providers and researchers as fatigue is a predominant symptom of long COVID.

Sahilbhaia, how do you pace yourself and manage the fatigue?
