i'm about ready to give up!

i dont know what to do anymore. i have fought with doctors and people telling them something is wrong for over 10 years. now i'm 24 and i can't do it no more. i had surgury on my neck in octb. and for fighting so many years telling these doctors there is something wrong. now that i proved there was something wrong with my neck the pain is still there and now there is more my heart keeps speedig up then it feels like someone punched me in my heart. then i gasp for air. now after thanksgiveing i woke up my toes and feet hurt soo bad. but i thought ohh it was just because i was on my feet all day. but they still are swallen and hurt soo bad when i walk it feels like i have walked on rocks for days. then the other night. my knees got really red really hot to touch and very swallen. and on my right knee you can see my vain like really big. then. the next day. the swalling went down alittle and the red went away. BUT now i have this big big bruise on my knee WHAT is wrong with me. I hurt soo bad everyday and my doctor just seems he dont care. he dont even care about what i told him about my heart he said " ohh everybodys heart does that" Really? cause my husbands dont do that. why does mine do that. i dont understand anymore how to keep my head up and fight. what would any of you do? i just really need some advise on this. cause no matter what i do anymore noone cares. i dont want stupid medication i just want to be normal. and have a normal life. like everybodys else. but i know its not gonna happen. no matter how much i pray and cry.
