Migraine, Auras, Anxiety, Depersonalization,Vision, Parasite, Ibs… please help?

Im 26 and have seemed healthy my whole life until recently. 6 months ago I was lifting a treadmill and felt a slight pop in my back. I began seeing stars and lost peripheral vision. Threw up for an hour and went to the emergeny room. They said my back might hurt next day, it did and i couldnt walk for a month and bascially figured out that I had a aura migraine. I’ve had slight weird symptoms since then like quick short brain rushes, and one week thought my phone was vibrating in my pocket but wasnt. I had my second migraine about 4 weeks ago but I woke up to it at 9am and wasnt as severe, i slept it off but felt hungover for 2 days. Then 2 weeks ago I went wakeboarding and wrecked alot and noticed I had alot of lake water in my nasal cavity and it had that bad lake smell that night. Felt drowned and definiately drank some.. Next day I seemed fine but was super sore all over. That night I had an aura so i popped 6 advil real quick and then the migraine came and it was somewhat bearable. I went to bed and the next day I woke up and I didnt feel right. This went on for two weeks, My vision seemed off almost like I was hungover or stoned or have a spot on my eye, or feeling like i was in a dream, I felt dizzy and vertigo but my hand eye coordination was fine so maybe its more like lightheadedness. The only thing closely describes it is an anxiety disorder called depresonalization. I kept thinking I’d wake up and it would go away but it didnt. I slept all week 14 hours a day and was still exhausted. I got blood tests and everything came back perfect, standard eye test came fine but i felt dizzy. I had an MRI on my brain and that came back fine too. Chiropractor said I have a very stiff and straight twisted neck and it looks like a herniated disc in lower back on the xrays. I play every sport though and my back hasnt all bothered me that bad. Ive gotten 2 adjustments since and starting to wonder if I even need to be going there cause i dont really have that bad of pain. I got a massage as well and she said I was unbelieveably tight. I noticed that it could be anxiety because I started spinning in the room when i saw xrays and had a panic attack, which has never ever happenend to me before. I also had clay colored bowel movements for a week and now its pure green and small bowel movements. I decided that since my mri and blood test came back super healthy that I have to have an anxiety disorder. I always have thought to have ADHD and my head talks to itself but I have always just felt pretty chill and used to it. Ive smoked weed for 6 years and never had anxiety problems except for the sometime paranoia after a smoke. Ive always been kinda hyper, funny, and pretty happy. I just got out of a 2 year relationship and have been sad at times, but never ever thought that anxiety was there or that I was sad more than the ordinary. I had rouger break ups when I was younger that I learned from..I never even thought anxiety even made physical problems as debilitating as vertigo or making me as sick as ive been if thats really what i have. I was reading so much symptoms on the internet I think I drove myself to panic attacks and anxiety, but i think its natural to start to flip out or have anxiety when your eyes dont work and you feel like you might die or your vision will never change. Because the first few days after that migraine I didnt have anxiety, just dizziness and weird feeling. Also around town people have been getting insane ragweed allergies, people who have never had them, I have a terrible nose and mri showed minor deviated septum. Ive always had bad colds in winter and allergies all summer. I decided to get sudafed, eye drops, chiropractic adjustments, massages and concentrate on thinking positive and laying on the floor and breathing well when I felt more dizzy. I stopped weed and alchol to try to take away anything that has an effect on anxiety. I felt the visual problems go away a little bit after 2 days of that but had alot more panic attacks. My mom gave me an adderrall to try from one of her friends cause it couldnt hurt to see what happens… I went to a festival after that and had a few beers and felt good then anxious then good then anxious. I met up with a friend later and went out and got wasted and for once actually felt like I was feeling kinda normal. I had brown stool finally last night after drinking and woke up hungover today but I feel like alot of my visual stuff and panic is gone.. I was even able to go to work today first time in 2 weeks. I decided my green stool is very unexplainable so I looked for answers today and read about having human parasites. I ingested a ton of lake water when I was wakeboarding and I found that some lake water parasites have caused people insane anxiety and vertigo ajnd neck stiffness and confusion. I have almost every single symptom of a parasite except diarrehea. That could also explain why after 2 1/2 weeks I
