What could be the cause of my chronic fatigue?

I'm 21. Since I was 15, I have been experiencing symptoms such as: tiredness, sleepiness, muscle weakness, tossing during sleep, difficulty waking and getting out of bed, difficulty concentrating, morning tension headaches, stuffy nose with being more severe in the morning (got hit hard in the nose around age 14), dry lips, and dry mouth and lips when playing sports.

I have had cold intolerance since maybe age 8 (I love taking long hot showers and hate coming out of the shower), high blood pressure since maybe 19, and a heart murmur since I was born (doctors said it was normal).

My lab results:

Nov. 15, 2011

THS: 4.36

T4: 8.33

Cholesterol: 136

Albunin/Globulin ratio: 1.61

HDL: 32.8

Dec. 28, 2011

TSH: 1.65

T4: 9.17

Total T3: 1.06

Albunin/Globulin ratio: 2.04

March 1, 2012

TSH: 2.97

T4: 7.99

Total T3: 0.76

Electrocardiogram (2007): Doc said normal.

Echocardigram (Nov 2011): Doc said normal.

Now the doctor has now referred me to Cardiovascular Disease.

Also, this doctor that I have now all she did was checked my heart with a stethoscope during the 5 visits. That's all she did to my body and nothing more.

I'm thinking that maybe it's my chronic stuffy nose that's causing all this?
