Me today..wondering about tomorrow.

So I work in the front and back office of a medical office in Monterey, CA.
I room patients, I give shoots, I do EKG's, take blood pressures, prick fingers for blood sugar. The whole shabang! Check this site out if you have something wrong and have no clue what it may be or maybe you have a clue http://symptoms.webmd.com/default.htm

I like people and especially helping people stay healthy, but often I wonder, is this it? What else am i supposed to do? Should I go on to be a nurse? A therapist? A Physicians assistant? A DOCTOR? Or simply stay a scrub...btw I love that show, it's got humor...something most lack these days. We will see I suppose. I will start up school AGAIN and add to my student loans AGAIN...we'll see whats in store for me. I'm never done learning but is simply smiling and charting it enough > ? I think that something will come to me soon. Ive seen everything from someone who just had a stroke, to surviving brain tumors, lung cancer and fluid in the brain. I see all shapes, sizes, nationalities and ages. I need a sign of what to do next...something out there needs me, some profession, I just do not know what it is.
