I had blood work done and d..

Ok, I've had some strange symptoms for almost a year now so I went to see an internist (doctor of internal medicine) and when I told him about my symptoms he decided to order some blood tests. I told him my main concern was on the state of my liver because the symptoms I've been having were sometimes indicative of liver problems. I also was thinking this since I had to have my gallbladder removed a few years before as it was full of gallstones and had become infected. Ok well these are the symptoms I've been having:

- fatigue even though I sleep at least 8 hours and sometimes 9

- frequent headaches

- nausea upon waking most days and it usally goes away later in the day but there have been days when it has lasted all day

- finally yellowish skin tone, which I didn't realize it was yellowish looking but some family members have commented on it and when I asked a few of my close friends about it, they said they've noticed a looked sort of pale

Are these symptoms of liver disease?

I know that yellowish skin can be caused from being jaundice which the liver would be the culprit....are the whites of your eyes yellow? headache, nausea and fatigue could be from anything.....i have that most days myself....would love to know the reason too.....
