My thoughts are torture.

     I have been very upset today.  My tiredness and breathlessness seems worse today at times.  I also have been having issues with going to the bathroom.  It started two weeks ago with loose stools, but they were thin and narrow, not their normal size.(sorry if this is tmi).  This weekend I can't even do that, I feel the urge to go, I get in there and I can get barely anything to come out.  Now I worry that my tiredness might have something to do with it.        I did something that is never helpful I went onto webmd and looked up my symptoms.  So now I am worried that I have Colon-rectal cancer because the thin narrow stools are a symptom because it is the stool trying to go past a tumor, also anemia (tiredness, breathlessness) is also a symptom. Also I know that blood in the stool is another symptom, I tried to look at the little bit I had but I could not tell, so I am not sure about that one.    So now I am completely freaking out, which is not helping.  Because then I lose my appitite(sp) and my stomach feel worse and I get diarrhea which at this point wouldn't be so bad so could go.  Now I am wondering what to do, I know that until tuesday there is not much I can do because Monday is a holiday.  Should I call my doctor and try to get an appointment, I know my blood work will not be back by tuesday, so they might not know anymore then I do at this point.  Should I try to see a Gastroenterologist because that is what they deal with, but I do not want to waste a specialist time if it is nothing.  But on the other hand if it is something I need to get it looked at.  I am confused.  I need help, am I freaking out over nothing or is it something I should be concerned about.    I could try calling the nurse that my insurance provides and see what she thinks.  I don't know, I just don't know what to do.  Please Lord help me know what to do.
