Diarrhea problems stopped, but I think blood in stool!

So I figured out my diarrhea problems are from stress and I've stopped worrying about it which has worked wonders on me. But today I went to use the bathroom and looked and i saw some red stuff in my poop...

The only red things I've eaten lately are a fruit cup with a red fruit in it, and some red gummies.

But this didn't seem...right. I saw little red things floating around and picked one up, I looked at it and it looked stringy?

I'm a very anxious person and this made me so worried. Usually I just have blood on my stool due to fissures but that's rare. I thought maybe it was the same old problem this time but no...it was inside my poop...I'm so worried....
