Systemic yeast or candida

Hello ,
I have a question in regard to candida, or systemic yeast. Is is neccessary to have cancer somewhere in your body to have systemic yeast? This past summer I had a strep, staph and yeast infection in my feet, I thought it was just athletes foot and scratched it, well it went to my hands, then I was prescribed Diflucan 3 times, several Antibiotics including Levequin which I suggest no one takes unless it is seriously neccessary due to the wild side effects I experienced. I was on Penn Vk, Gris-peg, Nizoral and doxycyline. Shortly after this I went to the doctor and asked if systemic yeast was possible and the doctor put me on a antidepressant thinking that I was a hypochondriac, the antidepressants made me worse. Since then I have developed what appears to be a yeast infection in my mouth (not majorly just obvious ) my hands looks yeasty, and my feet, along with my penis is now lightly redder than it ever has been. Could this be systemic yeast?
I even tried to get my doctors who I have floated around to to check me for cancer but they keep giving me this " your too young to worry about cancer" story with me being 33 yrs old. and I even told them about my mother and father both dying of cancer. i even tried to schedule a cancer screening in the same clinic that the doctor told me I was too young and they still have not called me back in two days for an appointment.
I am at my wits end, now it looks like my face and spots on my arms and back have itchy red bumps that come and go, I have even put vagisil and some womens yeast infection creams on these bump areas and it goes away only to return, so this should show them that this is a yeast infection but they think I am nuts.
I also have found that all they seem to want to do around here in Southern Illinois is out you on a dang antidepressant and tell you to go home and come back in a few weeks to check the results. Has this type of so called health care been experienced with anyone else on here.
Also do these symptoms neccesarily mean you have cancer in your body somewhere or could it be the yeast ? Also am experiencing tiredness, aches in the shoulder blades and joints, skin changes, frequent urination , thirst and craving sweet substances constantly with no weight gain. ALso I told them that from October of 2004 and the middle of Novemeber I lost aover 30 pounds and had some bllod in the stool prior to all of this starting but they keep passing it off as anxiety and depression.
Can anyone help me out there ?????
Sincerely, Illini Tweet
