bloody stool, acid refulx, and chronic abdominal aches

I recently graduated college and have no health insurance.  For about six months now I have been experiencing bright red bloody stool, and what I'm guessing is acid reflux (when I consume coffee or some kinds of alcohol, or vinegar, I immediately feel a burn reach the top of my throat if not completely regurgitated.)  I also suffer (sometimes severe) abdominal aches whenever my stool becomes bloody.  Sometimes I will not pass stool, but blood, instead (though not alarming in quantity).  Rectal pain is seldom present unless I eat an excess of spices.

I'm also a smoker of years, but very recently, it seems to be aggravating the condition, so I've cut back as smoking has recently triggered vomitting, strong cramps, and a sweat.  I'm aware that this could be completely uncorrelated.  I've also limited to my drinking to rare occasions, but it seems to have no effect on blood presence.

I am young and have been healthy my entire life.  I have a normal weight, low blood pressure, and am female. I also have a high fiber diet.  When I was younger, I was bulimic and abused laxatives for a period of a year or so, but I never experience lasting problems thereafter unless you consider now, half a decade later.

Everything might be okay, but I don't want to ignore warning signs that could lead to more serious problems later on.  Any suggestions of what may be happening?

Rectal bleeding is never normal and you should seek medical advice. You are probably too young to have the more sinister causes of rectal bleeding.  Type in rectal bleeding to google/yahoo etc to find out more.

A colonoscopy is the most comprehensive test - it may be worth trying to scrape up the funds in order to gain benefit from the reassurance that it will hopefully provide.
