IM EFFING SCARED!! Can Anemia cause petechiae?!?!?!?!

Hey,

I'm a 20 year old female and I honestly believe that I have some form of Leukemia... and I also believe that I am slowly, but surely, dying from this disease. Here are a few of my main concerns/symptoms and the reasons behind why I so strongly think this and in my head... know this:

- I have been bruising a lot more than normal for the past couple of months. I constantly have bruises and they are mainly on my lower parts - as in, my legs, etc.
- My body, also for the past couple of months, has been cramping and aching in random spots... from my feet, legs, back, shoulders, etc.
- This I noticed yesterday, but I found more today - petechiae, forgive the spelling. I have at least, well... around 7 of them (that I know of.)
- I seem some-what weaker than normal and kinda' off, like... fatigued. I look a little pale and I have these dark circles underneath my eyes. Oh, and yes, this all started around a couple of months ago.
- My periods have been a little off for a few-ish months, but... to be honest... I'm not too concerned about it.
- Once again, for the past couple of months, I sometimes get small and short headaches after I stretch, get up to fast, or go to the restroom.
- For years and year I've had an enlarged lymph-node right behind my ear (not on my ear and kinda' right on the hair line.) I also, have a thyroid nodule, which I've had for a few years... if not more.
- Around a month and a half ago, I got some tests done - blood tests: CBC, thyroid levels and some others, like iron. Results for the blood tests came back normal. I had an EKG and a pap-smear done and yup, all normal. The only thing that came back abnormal was my UA, which has quite a bit of protein it (around 100, or over in the trace amount.) No, I'm not pregnant... just to get that out there, but I did have a possible early miscarriage.
- Random, but my Mom is anemic.
- I suffer from sever depression, anxiey and other mental issues and that's also, another long story.

So, that's about it, really. There may be more, but those are the most important symptoms and what-not. I want everyone to know that I am making an appointment at a local doctors' office in my town and I don't have medical insurence; I would rather not get in to that because it's a long story all on its own.

Thank you and I appreciate your advise.
P.S. I don't trust those CBC results because of my current symptoms.
