Why do i have so many medical problems?

There probably isn't an answer for this....but I'm going to ask anyway. So ill start you off with the facts that im only 15 and im a girl. Just these past months i have been hit with all these medical problems, not to mention depression. So, i guess ill just list the medical problems i can think of (i cant remember stuff anymore). Alright, i have carpal tunnel syndrome, hip dysplasia, my right socket is too deep but my hip like doesn't go in all the way, my hips dislocate then relocate themselves, labral tear, scoliosis, anxiety (i get panic attacks sometimes and whatnot), iron deficiency, very low vitamin D, mono, hypothyroidism, a polyp on my gallbladder (i have to have surgery in a couple weeks), ingrown toe (they had to remove parts of my toenail twice. They stuck a 4 inch needle in my toe 5 times), my knees are not aligned right, ADD, migraines, cataracts, and im still waiting for some test results they had to take 8 vial's of my blood. I have other symptoms: zapping like sensations in my head, mild to severe pain in the upper right corner like under my right rib cage, mild to severe (usually severe) pain in the area under my belly button, when i go to the bathroom, its really painful because that's usually when the pain under the belly button is the worst and it feels like something is tugging from the inside. My bones always hurt i.e. my arms, fingers, thighs, hips, especially my knees and the tibia or whatever that is. I also havnt had a big appetite. And im so tired all the time most of the time i dont even have enough energy to open a door. Sooo yeah. Haha. I have a lot on my plate. I'm sorry if it seems like im a being a baby or im full of myself or whatever. I usually don't complain about these things but i just really want to know why all this is going on, and why all of the sudden? And im actually not overwhelmed, everyone thinks i am but im not. Im not scared either. Im just tired. Well, im scared about the surgery. But thats it. So, anyway, id just like to hear your opinions on why i have so many medical problmes. Thank you. (:
