LONG list of symptoms- Have any suggestions I can tell my doctors to look into?

I've been to doctor after doctor after specialist after specialist and after several years and thousands of dollars, they still have not come up with anything. So I'm asking here. Not to get an accurate diagnosis, but just asking people suggestions that I may bring up to my doctors so that they know where to stem off a research into.

Currently I see a regular doctor (everything else), Neurologist (migraines), Dermatologist (suspicious mole removal) and a Physical Therapist (cervicalgia). In the past I have gone for an MRI of my brain (nothing showed, but was over 4 years ago and things are much worse now), Upper endoscopy (for terrible stomach pains like stabbing and ripping out of organs, that was also organs below the stomach, as well. Nothing found over 3 years ago), Ultrasound of my stomach (more research into stomach pains, nothing found over 3 years ago), and Echocardiogram (after heart attack like reaction at age 19, nothing found). As a kid I was always sick. The only serious medical problem that I know of during childhood is that I had a bad fever convulsion at age 2. And I was always getting in trouble with how many sick days of school I was taking. Never having to repeat a grade, but just making the cut each year. And my health gets worse and worse each year. I don't think it's all in my head and I'm making up these illnesses. If that were the case, I would be able to take over the counter medicine and think it's fine. But absolutely NO over the counter medicine works on me. I might as well eat a candy bar to make me feel better. So here are my symptoms, in no specific order:

--Migraines (basically continuous. I have been put on 4 different prescriptions and only one works. Zomig. But that you aren't supposed to take more than 3 times a month, and are only for severe migraines, even though the Neurologist prescribed me a refill amount capable of me taking it 365 days a year.)
--At least 4 or 5 times a day I have to take a big breath in and breathe out deeply. Even when I am sitting down doing nothing. I'm just forced to take a deep breath.
--I get colds in heat at first. When entering a warm room or higher heat outside I start sneezing like crazy. I do this EVERYWHERE so it's not an allergy to one specific thing. This goes away within minutes usually. Though when I went from OH to AZ in the winter, I was sneezing constantly for over 2 hours after landing in the warmth. Lungs burning and everything.
--I have cold-like symptoms probably at least 250 out of the 365 days of the year. Colds in the summer are more common than winter.
--Sometimes it feels as if someone is squeezing my heart and it makes it difficult to breathe.
--I have called it my stomach, but evidently it's below my stomach. Like kidneys and bladder or something. But I would get terrible stabbing and ripping out pains almost twice a week, which would leave me bed-ridden and in screaming pain. I am currently taking birth control and have not had my period for over a year. This is a temporary band-aid and has worked really well, until recently. Every now and then I get that pain just not as severe.
--I get UTI and yeast infections like I get paid to get them :/ It seems like it's almost constant. I would say almost once a month. The very least, once every two months.
--I get dizzy a lot
--Nauseous a lot
--Memory loss (not really severe, but it's affected my work and personal life negatively)
--I don't do too well in the sun. Start having trouble breathing and get dizzy and whatnot.
--Hyper ventilating problems.
--Loss of interest in stuff.
--Loss of interest in sex (started about two-three months ago)
--I have problems falling asleep
--Every single night I wake up in the middle of the night between 3-4 am (for almost 2 months, now)
--Sometimes I get the feeling like someone is squeezing my lungs and I have difficulty breathing.
--Bad stomach problems
--When I know I'm going somewhere without a toilet near (like a park) or when I go out in public where there will be people (like a party or something) I get really nervous that I won't have a bathroom near and I will have to go, so my stomach starts hurting and I have to go to the bathroom like 7 times before I leave to go places. It's getting a LITTLE better, like only 4 times, but it's still pretty bad.
--I've been very on-edge lately and cranky/depressed.
--Random mood spurts where one moment I will be crazily hyper and in a good mood, and others (after hearing a non-nice comment or something) I instantly go to a bad mood and get all b*tchy.
--Randomly I get VERY hot, then moments later I get VERY cold, and so on and so forth.
--When I was younger I would always get strep throat. Like at least twice a year. I don't get them as often (if I do, they go untreated)
--I get very nervous easily lately. Ex- My bf and I stopped at a "bog" trail. It was surrounded by trees, weeds and such and the bride/path was very narrow. Normally, I l

I forgot to mention that I recently went to the doctor and got diagnosed with a bad UTI and bad yeast infection after the UTI. The urine came back that I had a ridiculous amount of Protein in it (also had a lot when I went tot he ER after my near-heart attack in early March). And 100,000 colonies of e. coli grew overnight in it. During that UTI for almost 2 weeks I had terrible pressure near my bladder area just after finishing peeing, and would bleed. A lighter and thinner blood than period blood. It stopped after 3 days of taking the UTI medicine. And my urine is always cloudy and foamy. Has been for a while. I researched high protein levels and evidently those two things are symptoms, too.

I mostly skimmed, high protein levels is shown to cause migraines, that is probably your issue there.. I'd definitely look into kidney disease. high protein is a sign of that and some of your other symptoms.
