Weakness still present after months of treatment ?

So i think i am look for some assurance from this sub from ur own personal stories, given that doctors dont know much abou it.

I have been takin injections since october and coofactors. All the symptomps are gone except for low stamina. I get tired very easily. Recently i have been doing a bit more activity than before. Very little though. I have suddenly memory loss and today felt like my body would shut down. No pain or discomfort. Just my body wanted to rest as if I have been doinv a marathon. Even my eyelids feel heavy. Is this part of the recovery process ? I cant even think to schedule a doctors appointed for this, as I m sure they will say its okay.
