Hello, Artesh. I live in the US, so I'll say what I think would be the right thing to do in our medical system. You will have to figure out how that translates to the medical system in your country.

Here, you would first go to see your primary care physician. You probably would be sent to have psychological and neurocognitive testing done and probably also to see a neurologist.

That is my best understanding of what route to take to try to find out what is going on. The way you have described your symptoms make it sound as though there is certainly a medical basis for them, and that you are not suffering from the usual type of depression.

I am not a medical doctor, so that is just my best guess. I wish you good luck in trying to find out what is wrong and how to deal with it.
