Different Form of Life...

Hello, as you can see, I'm new. I'm 20 years old and currently
in a recurring confused state. I honestly don't know what my
problem(s) is(are) and if I can eventually overcome...This...
I spend the better part of my day simply thinking. Thinking
about past and present experiences and trying to figure it all
out. Rather then functioning in the moment, I find myself
drifting off into my own private world. When I'm in this state
i feel I have a better understanding of people and the different
processes which govern them. This excites me and I start to
feel euphoric (i don't use drugs). Talking quickly and having
debates with people, testing there intellect and blahing...
(you must be thinking I'm a nut case, but it's sadly more
complicated). I constantly analyze each situation and try to view
it from different perspectives. Revelations occur and I feel
i grow in wisdom through these processes, but then...I wake-up
(figuratively and metaphorically). This is when I start to feel
confused and depressed, because I realize I'm an fool...Why?
I excel in mathematics and creative arts. I am able to logically
reason and yet, I know things...Even-though I don't, because i
never seem to complete the puzzle. It always seems to morph...
Therefore, I am never able to explain...

I stopped associating with my friends a couple of years back. I
have no friends at the moment, nor do I want or need any. It's
depressing, because I can still remember the good times. Having
fun...Such sweet moments in life, twas pure joy. Now, those
experiences turn on me-'the Truman show' comes to mind (you know
that movie with Jim Carey). I feel like I've lived many lives.
To bad, life's so short...To short for people to waste there time
on me lol...

I feel like I have some sort of disease, which is making my brain
malfunction.

I've recently had a mental evaluation done. It took many visits
but in the end, they have not reached a diagnosis-they say something
is not right, but they have no clue as to what it is...Great...

I'm still young, so I have hope. I don't know how I can benefit
from posting this, but it's worth a shot. I still have hope, after
all I'm still young.
