Woah, slow down that train of thought!
Firstly, you are unbelievably far away from having a bag. Most folks diagnosed with UC or Crohn's end up never having a bag, so even if that's what you have, the chances are still much higher than not you will be bag-free your whole life.
Secondly, don't google. Seriously. Don't google. Google just has a knack of leading you straight to the most dire cases or telling you will die. Which brings me onto point three.
Three, blood in the stool terrifies many people. It just looks scary. But in IBD, it's actually a fairly normal symptom - extremely so in UC. It's not benign as such, but it's also not a sign of anything life threatening. There are times when it can be dangerous: if the blood is black (a sign of bleeding higher up in the GI tract, which is more serious) or if the blood is literally pouring out into the toilet bowl. But usually it's just an unpleasant byproduct of having inflammation and ulcerations in the bowel.
Four, your doctors are idiots to ignore blood in the stool. I have just said it's usually not life-threatening, but it's also not normal either. You could just have internal haemorrhoids, but the other symptoms make it less likely - and besides it's easy enough to check for haemorrhoids. Other possible non-IBD causes include anal fissures (can be a part of Crohn's as well though), colon cancer (virtually an impossibility in somebody your age), diverticulosis (again, an affliction of the elderly), or intestinal infections which mimic the symptoms of IBD.
Five, please find a doctor who will run the relevant tests, eg stool tests, blood tests, colonoscopy. If it helps, take somebody along with you for support and try not to look/sound scared in front of the doctor. I know that sucks, but the calmer you can appear, the harder it will be for them to fob you off with 'stress' or 'IBS'.
And finally, don't worry about theoretical, long-term risks, like cancer or osteoporosis. You would have to have pretty severe disease for decades to have an increased likelihood of those things. Or, for osteoporosis, to be on steroids long-term.
Good luck; I hope this helps at least a bit...
