Any ideas of what is wrong with me?

Im 15 and have a bunch of medical problems but none of them explaine these other symptoms that i have. You know how sometimes when you get up fast you get light headed and your vision is all like black and spotty? (maybe its just me haha) Well i get that randomly, not just when i stand up too fast. I also get light headed and dizzy a lot. I have a lot of stuff (symptoms and whatnot) and i don't know which ones to say so I'm just going to say them all haha. I have really bad sharp pains (that come and go and only last for about a minuit) in both my left and right ribs. I bruise easily. I get really bad migraines. Iv been coughing my head off and its a really bad sounding cough. My bones always hurt, especially my legs. (I do have hip dysplasia, my joints are too loose and i am double jointed. If they have anything to do with it). My nose is always stuffed up. A couple times before, i have like blacked out, i forgot everything. Who i was, where i was, whaty i was doing...everything. But that only last like a minuit or two. And a couple of times i have had this like zap thing in my head. Just like all of the sudden, from a noise or a voice, my head gets a shock. A really big shock. Im also depressed. I get pains in my belly, where my belly on is and under my belly on. I'v had rectal bleeding a few times. When i cough it hurts my chest. I also have cataracts, and i'm going to this big hospital to be tested for albinism. (I dont have red eyes i have blue eyes. And i dont look like the pictures on google. I just am really sensitive to light, have really pale skin and light blonde hair). I also have a shortness of breath a lot. When i run but also when i just go up stairs and sometimes out of no where. I have a metalic taste in my mouth often and sometimes (more recently) i have had like acid reflex i guess, my saliva burns my throat and mouth and stuff. Umm that's all i can think of at the moment but i know there is more. Oh well. The reason im asking this question is because my doctors (yes, multiple doctores. I have many haha. But im sure everyone has multiple doctors) aren't going anywhere with these symptoms. I am having a scope down my throat next week so i will see what that turns up. So any idea at all of what is causing these symptoms?? The pain in my head and in my bones is so bad sometimes i just can't take it (And i have a high toleration of pain. I'v gone through so much. Including that lazer thing on my face where they zap you. It felt like a bunch of rubber bands snapping my face. I had that done 15 times. On my whole face. Because i had really bad acne and still have mild acne. And other stuff which i don't really want to talk about. Plus i am very very accident prone. I can't go a day without getting injured wether it be a paper cut or a broken finger. So anywho, answer my question please? And only SERIOUS answers please. thank you (:
