What is wrong with me? Feint

My vision became staticy, I saw a bunch of colors my ears began hearing static, I felt dizzy. Light headed. Everytime I ate something after a few hours the initial bite would hurt my stomach with a sharp pain, be it healthy or sweets.

                My body had gone a bit cold, and I can hear my heartbeat so clearly throughout the night into the morning. I could not find peace.  It is stagnant, and my body felt unmoving as If the bloodvessels are frozen.  I couldn’t focus on anything, no matter how much I read and sat there my brain would not absorb anything. I don’t say this as many complain ‘I can’t focus,’ when they truly can they are merely inconfident, no I mean I couldn’t physically concentrate.

What is wrong with me?

I felt claustrophobic around people, and whenever someone came near my body was sensitive to their presence.  I don't usually feel claustraphobic like i did. 

Oh, and i never get pimples but lately i have had more which might factor into what this is? Perhaps related to hormones or emotions? I am not sure. If you need more details let me know. (I put it into this category because i have no idea where to put it, and i have felt feint because of these symptoms)

hiya have you looked into lyme disease ? these symptoms seem to fit this. there is a lyme forum that alot of people with lyme can advise you. if you need further advice on lyme or autonomic neuropathy/ disfunction inc websites and specialist private message me and i can give you any details you need

I am fairly certain it is not lyme disease. I have been extremely anxious and afraid of school and after looking through some different types of relations i believe it is a neural thing. What i believe this is is this "Neurally mediated hypotension," 

Ever since i was little I have had to hold in my emotions, i was not allowed to cry. So whenever i feel deep fear it eventually builds up and this happens usually. Not to mention the worry over not doing well in school and a sense of anxious desperation to pass.
