I feel tightness, compression inside my skull, like somebody trying to squeeze my brain, for a really long time and  it never goes off. It doesn't hurt but feels extremely uncomfortable. I also suffer from derealization. I sweat profusely and I am always anxious. If somebody suffered from them, how did you recover? What medication did you take? I'm taking Clonazepam 0.5mg and 150mg Venlafaxin for  a week but doesn't help.
