Weak and tired

I feel weak and tired alot. I've seen my doctor and they have taken blood work.  was told that everything was ok, but I'm still feeling weak and tired alot. What else should I be concerned about?  I also get sick to my stomach when I eat anything at times. I've also told my doctor this but she told me just to not eat and lay down,but I don't do that. Is their any reason I feel this way or has anyone else felt this way?

I felt similar to this when I was depressed. The tiredness and feeling weak and sometimes sick. Are you under a lot of pressure at the moment? are you content or have you been feeling down lately?
