Hi so yesterday I hit my head, not too hard, didn't hurt much but of course I was very anxious! Yesterday at canoe polo another boat also came into my side lightly, also didn't hurt and I didn't think much of it till today when I had very dark poo. I googled what dark poo meant and it said a possibility was internal bleeding in the stomach...so anxious and it's hard to sleep. But another possibility for my dark poo could be that I've eaten lots of Oreos over the past few days??? what do you guys think?? Anxious!! And my OCD makes it hard because I have to do all these extra things to improve my chances of living. That probably doesn't make sense but...whatever. Thanks.
