I have to agree that I don't think it's anxiety but then again, I'm no doc. Are you on any blood thinners or aspirin? Don't meen to get gross here but check for dark, almost black stools or blood streaks. You could have an issue with blood thinning. I would get a PT/INR blood test too to see how thin your blood is. Definitely visit your GP!
