Lyme, CFS, or...?

Hello all,
I was briefly on this forum about 9 months ago after being very sick and getting a positive ELISA test but then a negative western blot. I was very sick for awhile before this happened but ended up only treating with 6 days of doxycycline due to being told it was not lyme.
So I went on my way and actually felt quite better during the fall. But now I am starting to decline again. It's hard to describe all of my symptoms because they are so random. I am always fatigued, but not just tired. Sometimes it takes all of my strength just to sit up straight or keep my eyes open. When I get fatigue like this, it comes with horrible body aches, which are the most painful in my legs. It feels like I have the flu. I have not been taking my temperature but this week I was having worsened symptoms and felt like I had a fever yesterday with these symptoms. This leads me to believe a low grade fever often accompanies my fatigue and aches but I just don't realize it. I get headaches, not daily but often. Another thing that has really been troubling me is heart palpitations. Yes I am an anxiety sufferer but even when I am completely relaxed I have a heightened sense of my heart beat, like its beating really hard. I also get flutters in my chest too. I have extremely cold and clammy hands and feet. I've also been feeling more dizzy upon standing or just when standing and walking in general, which is a pretty new symptom. Two more things I think are important: severe chronic constipation which I've had a colonoscopy and endoscopy that showed nothing. And lastly, recurring vaginal yeast infections and discharge.
So I am very frustrated and confused right now. Does this sound like chronic fatigue syndrome or could it be lyme disease? I am struggling with what doctor I should see. I am a college student with no money and no supprt from my parents who think I'm crazy, so it's almost impossible for me to see these more alternative doctors. Any doctor recommendations spanning from the Philadelphia to harrisburg pa region?
Any advice would be greatly appreciated!

I had it checked about a year ago when my symptoms got worse. It was normal, but the numbers were a little on the high side so I would like to get it rechecked.
If I wanted to get the igenex test should I go to a certain doctor? Infectious disease doctor? My current pcp is no good and I'm assuming not all doctors will be open to ordering that test.

Thank you for your reply! I did tons of research back in the summer when I first thought I had it. I will shoot you an email!
