Does this sound like an Anxiety Disorder?

My head constantly feels pressurized, like the pressure is building up (doesn't hurt, just extremely unconfortable and never ends has been going on for 6+ months now), my eyes feel like they are either going to go cross-eyed or sink into my head (left eye feels cock eyed and right feels corss eyed) Extreme depersonalization, I feel as if I am in a dark dream, everything feels so fake, I can tell that its reality it just doesn't "feel" like reality. because of this "brain fog" I cannot think and I feel like I am retarded sometimes. I have lost all mental clarity that I ever had and my sense of smell / taste (its not lost just extremely dulled) like is said all of this has been going on for 6+ months and I have been suffering from mild depression because of this. I am NOT on any medication and I am only 19 years old with no health insurance. I feel like a 90 year old man because of these symptoms including others ranging from my body hurting / feeling weak, breaking out in cold / hot sweat spontaneously, feeling dizzy / faint, and nauseas 70-100% of the time. if this anxiety than how come it happens when nothing negative / stressful happens? It just happens out of no where no matter what I am doing. please tell me if you can relate / help and will the "brain fog" ever go away and my mental clarity ever come back? please Help.. Thank you!

P.S. all the mentioned symptoms get considerably worse when the head pressure intensifies and sometimes I get sharp brain pains (yes brain pains not head pains, they feel very deep) my head also feels very heavy at times as if I have a major cold.

I often feel exactly like that, check out OCD.

Anxiety can happen at any time, it's very hard to pick point the trigger for it. You could be just sitting at home watching T.V. I've had anxiety for 9 years now, I can remember when I first started getting attacks, my head used to feel very strange as well, kinda hard to explain, like me brain was trying to escape out of my head. I don't get it anymore.

De-realisation is another thing I get as well. Strong sign that your stressed out.
