I don't know what's wrong with me

I'm 23 years old, and until late june of this year, I never had any major health problems. Just 2 months before the first "event" I was honorably discharged from the Marine Corps.
Ive had headaches for about 2 years after a car accident, but military docs just gave me otc headache pills and told me to be on my way. Sometimes headaches last up to 48 hours with nausia and dizziness. I know that cant be normal.
The first time, I was participating in a river float down with friend's, and after being in the Arizona summer sun for 4 hours, I was a bit dehydrated when finished. When it happened, my friends and I figured it was a one time thing and to stay better hydrated. But a week later, another seizure/event happened.

They occur every 3 weeks or so, and unfortunately due to health insurance, I won't be able to get any testing or medication for this until Jan 2015. I'm in college, and a mild one happened in the middle of class (leaving me pretty embarassed). Now its escalating to where I also have these "zone-out" kind of episodes, from what my classmates tell me...they have said Ill zone out for up to 20 minutes, unresponsive to sounds or touch.

I've never felt so helpless and not in control over my own brain. I have random bruises on my arms and legs, always feel exhausted from my muscles being so flexed during the events, and last night woke up with a swollen/busted lip.

I just want it to stop, or at the very least know what's going on.

I was taken to the nearest urgent care when it happened in class, a doctor looked me over and was able to give me a referral to a neurologist, however she said the testing I need will rack up to thousands of dollars without insurance. And she can't even start me in any type of medication without the eeg. Until then, I'm told to keep a journal of how I feel before and after the events.

It took me a while to just get in the system with BCBS but they said they won't legally begin to cover me until jan 1 2015, due to some rule about it being more than 30 days of me going to school after my discharge.
Thank you, I'm doing everything possible to keep safe, and luckly I'm still doing exceptionally well in school. Ill be sure to post updates.

Some people have hypothyroid issues after automobile accidents. I'm assuming they did CAT scans and an MRI to rule out structural abnormality. Sodium levels must be regulated constantly. Too much sodium is bad, too little sodium is bad. If your events are happening on a cycle, they are most likely either hormone related or directly related to the life cycle of a parasite. I would investigate both for now.
