Talk to Psychiatry on Neurology

I had severe depression long time ago then I started to develop some problems. I have extreme drowsiness all the time no matter how much I sleep i feel tired all the time, my taste and smell has been changed i don't know what I'm eating if something smells tasty I smell it bad same is the case with taste. I feel difficulty opening my eyes due to severe drowsiness. I sleep for more than 12 hours daily but still feel like I haven't slept at all. i have developed dark circles around my eyes. my MRI report is normal with and without contrast. I have consulted many neurologists but they can't understand my condition. I'm suffering from this condition since 6 years. I don't do any job because I feel sleepy all the time I can't open my eyes due to extremely high drowsiness. I can't focus, having memory problem and I don't reply to someone immediately when someone talks to me. having sleep drunkenness and brain fog. can any neurologist solve my problem.
