anxiety or something more?

i've been suffering from what ive been told is anxiety for about 6 months now.it all started with terrible panic attacks which i would get every couple hours and it got to the point where i was so shaky & weak that i couldnt even stand up.i have many problems with sleep and get an average of 5 hours on a good night but often less.i almost always have body tremors and my vision is constantly screwed up,my eyes are very sensitive to light and any light that i look at has a very large halo and rays that come off it(as if when crying).i also see afterimages from looking at anything for about 2 seconds and they often are in opposite colors (ex. a pink object=green afterimage,blue object=orange afterimage).just today i noticed while in the shower that any object i moved had a flourescent aura(my hand for example would be a bright purple on one side and bright green on the other)i know i sound crazy but i really just need answers.i also constantly have headaches and a floaty feeling in my head as if my brain is moving around but i recently started taking omega 3 pills which have seemed to help greatly.i experience depersonalization every now and then but this whole thing has caused life in general to seem useless to me.im not even sure if i believe in god or an afterlife anymore and i constantly think about death and where im going in life.btw im only 15 and i havent been in school for about a week now bc of this.ive barely ever drank and the only drug ive ever done,if you consider it one,is marijuana and all these symptoms started right after a bad panic attack i had from smoking which ive stopped completely.i also have have high sugar levels and my good cholersterol is low while my bad is high,yet im nowhere near an unhealthy weight.lately ive had chest pains and although these are all anxiety symptoms,many such as the vision i havent heard of and i am just worried that there is really something wrong with me.please either reassure me or tell me what else this could possibly be.

whoa...lots going on...well we are on the same boat..i 2 suffer from panioc attaks, and is so debiliating...makes me weak anad exhausted and my muscles ache from all the stress and anxiety...all you can tell yourself is that its the anxiety talking and try to not think about it, even though every little thing had u paranoid... i rarely sleep well and can't seem to concentrate on something that can comfort me while i'm panacking...one thing leads to another and i panic....but i have been dealing with it, and still continue to feel anxiety and depressed b/c it is hindering me from actually living...im trying not to take any drugs to correct this, but you may want to look into that to help control your anxiety.  you are way to young to be stressing, try to go back to your regular routine and go out friends, go watch movies, sports, or whatvever you did before all this...don't be afraid that your going to panic, fight it and tell yourself it's all ok.... good luck!
