Fatigue, pain, anemia, swollen lymph nodes, nausea, etc, does anyone have any advice?

I have been feeling very sick for several months now, and it has been progressively getting worse. I feel tired all of the time, I am very weak, my anemia has gotten worse, I've developed fasting hypoglycemia, my lymph nodes get swollen off and on, they have been swollen for over a week but without a fever. I cannot eat much as I have no appetite and feel sick when I eat (sometimes to the point of vomiting). I have lost some weight from not being able to eat much. I have a few petechiae on my arms, a couple on my chest and one on my back (this one's the newest about 1 wk old). The first one (on my chest) appeared about six months ago, and the other ones have appeared slowly one by one since then. I don't have heavy night sweats, but I have begun to sweat more in my sleep (which is abnormal for me) with my hair being damp in the morning. I have a lot of pain in many places, throughout my lower back, in my arms, and in my legs, hips, toes, fingers, wrists...the pain has been getting worse and more widespread. I have a lot of pain in my abdomen. I also get a lot of pain in my groin, I'm not sure if the lymph nodes down there are swollen but it sure hurts. I'm going to see an Internist on the 8th, should I ask him to check me for Leukemia or does anyone think I should ask something else? I don't want to sound like a hypochondriac, but I'm just really miserable and getting worse. I do get frequent infections that the urgent care is never able to diagnose ("It's some kind of virus, we're not sure which one") but give me medication for.
