Okay, what gives?

I have been feeling bad for quite awhile now...several months...and the pain and swelling in my right index finger joint finally drove me to see the doctor last week.

I told her about my finger, my knees (which hurt every day now), my lack of energy and general fatigue. She is a wonderful Nurse Practitioner and very responsive. She ran a battery of blood tests and I got the test results back today.

Everything is normal. That's a good thing, right? Then, why do I still feel so bad? Why is my energy through the floor? What am I doing wrong? She wrote a note on my test results that basically said if the fatigue persists, we can go ahead with a referral to a rheumatologist for more tests. But I'm just not sure what to do. I just want to feel better...
