Totally disempowered

[asdf]

I've now been feeling increasingly disempowered for several years, but the situation worsened quickly during the last twelve month and seemed to reach some kind of climax recently. Unfortunately, I don't know the reason for this situation but perhaps someone else can give me a hint here.

About me:
Actually, I could be a very happy person. I'm visiting one of the world's leading universities in my field, have great job perspectives, get decent support from friends, my university and my family and I'm achieving decent results in what I am doing.

However, I am constantly feeling like I'm some kind of zombie or I'm stuck in a non-lucid dream. My entire mind is messy and unfocused, everything I perceive is blurry. I am a very intuitive and analytical person - but on the other side, my abilities to perceive and feel seems to be underdeveloped. I am procrastinating even at things I like to do, I am constantly nervous but at the same time also tired. My whole life seems to be very superficial

I've been talking to tons of psychologists, went to church, moved to other countries, read tons of personal developing stuff, but nothing seemed to help. In contrary, my mind even got messier than it was before.

I know that this post is rather messy and not actually saying much, but that's mainly due to the situation - so please feel free to ask questions.

Does anyone have any idea what else I could try to get a clear mind and feel empowered again?
