feeling really odd, dizziness, feeling sick, blanking out, a few little pains in stomach

For around a year i have not felt right, ive had pains in my vagina, ive seeked medical advice with my doctor for 19 years , i still experience a few little pains now and again, not so much as i used to, i must have seen my doctor around 4 times, in an attempt to find something, which my doctor always puts down to bacterial infections how ever

i dance- i have to work out once- twice a week , which i keep having to not go due to me feeling extremely dizzy, last couple of times, i have blacked out and almost collapsed, i get pains while dancing which i feel is my body telling me to stop, i constantly feel tired and for the last 3 days i am beginning to feel concerned for my health

last night as i lay down in bed, my head felt heavy, i felt like water were trickling down the back of my head and i couldnt hardly be bothered to speak, i honestly thought i would be having a stroke
the night before that i lay in bed and my stomach kept turning over as though i was about to be sick , i had to take my clothes off in bed as i felt uncomfortably warm- usually i like to be warm, but this once i couldn't stand it and were tossing and turning all night, i havent had a temperature, i don't feel ill at all, i just feel really odd in myself,

for the last three days all the day i have felt lathargic, having dizzy spells, to the point i will be looking at my partner but not actually being able to see him, i completely black out, i feel a little unsturdy on my feet and even layed down i feel a huge weight, ive been having coffee today and can barely lift my cup up to my mouth, i can not explain how i feel, ive been experiencing , nausia, dizzy spells, a few headaches- nothing major and tiredness, ive felt like calling NHS direct to see what the outcome will be, i really dont want to go to my GP,
also im turning my nose up at food, i am not pregnant !
i cant put on weight at all, i am usually a food aholic, but i am still 8stone,

i don't know what is wrong with me, i feel a little shortness for breath at the moment, and i have been sat down all day !

im so sorry about any spelling mistakes, but i don't fancy correcting myself ,
