LIGHT HEADED/DIZZY,WEAK,NUMB FINGERS/TOES,VISION PROBLEMS,TROUBLE FOCUSING ON THINGS,SHORTNESS OF BREATH?

HELLO, I AM 30 YRS OLD AND HAVE BEEN HAVING THESE SYMPTOMS GOING ON FOR ABOUT 10 YRS NOW BUT THEY HAVE RECENTLY GOTTEN WORSE OVER THE LAST FEW YEARS. I AM DIZZY/LIGHT HEADED EVERY DAY BUT IT SEEMS TO GET WORSE AT TIMES. SOMETIMES ITS SO BAD I FEEL LIKE IM ABOUT TO FAINT. MY FINGERS AND TOES GO NUMB AT TIMES FOR NO APPARENT REASON. MY VISION GETS BLURRY AT TIMES AND ITS HARD TO FOCUS ON THINGS. I HAVE NO ENERGY AND HAVE TO FORCE MYSELF TO WORKOUT AND WHEN I DO SO THE LIGHTHEADEDNESS AND VISION GETS WORSE. I HAVE HAD A FEW EPISODES OF CHEST PAINS THAT WERE SO BAD I WENT TO THE EMERGENCY ROOM DO TO FEAR OF A HEART ATTACK. I HAVE HAD MY HEART CHECKED, A STRESS TEST,ECHO, AND HAD DYE PUT IN MY VEINS TO MAKE SURE THEY ARE NOT CLOGGED. IT ALL COMES BACK OK. I HAVE ALSO HAD AN MRI AND BLOOD TESTS THAT COME BACK OK. THE DR CHECKED TESTOSTERONE LEVEL AND CAME BACK OK. THE DR ALSO CHECKED MY GALLBLADDER DO TO THE CHEST PAINS AND IT CAME BACK OK.WHEN I HAVE THESE FEELINGS I GET SOMEONE TO CHECK MY BLOOD PRESSURE AND BLOOD SUGAR AND BOTH ARE NORMAL. I THOUGHT MAYBE BLOOD SUGAR DO TO THE FACT THAT I GET TIRED AT TIMES AFTER EATING SOMETHING SWEET. THE FEELING IS KIND OF HARD TO EXPLAIN...ITS KIND OF LIKE IM NOT GETTING ENOUGH BLOOD FLOW/OXYGEN THROUGHOUT MY BODY, ITS HARD TO FOCUS ON THINGS AND SEEMS MY MIND IS CLOUDY AT TIMES. I KNOW SOME OF THE THINGS GOING ON CAN BE ANXIETY FROM BEING WORRIED ABOUT WHAT IS HAPPENING WHEN I GET THE CHEST PAINS, BUT SOMETHING HAS TO BE CAUSING THESE THINGS TO HAPPEN OTHER THAN ANXIETY. SOMETIMES A SYMPTOM THAT GOES ALONG WITH THE BLURRED VISION IS IT SEEMS LIKE A WHITE FILM IS OVER MY EYES WHERE I HAVE TO BLINK A LOT OR RUB MY EYES TO GET IT TO GO AWAY. THESE THINGS GOING ON HAS BEEN EFFECTING MY LIFE. I CANT DO AS MUCH WITH MY KIDS AS I WOULD LIKE TO AND IT SEEMS LIKE EVERY TIME I GO IN TO GET SOMETHING CHECKED WITH THE HOPES OF FINDING OUT WHAT IS WRONG I HAVE TO START OVER BECAUSE IT CHECKS OUT OK. PLEASE IF ANYONE HAS ANYTHING LIKE THIS GOING ON OR ANY INFO ON THIS PLEASE LET ME KNOW. THANK YOU AND GOD BLESS.
