Worried but don’t know what to do?

Hi, I have recently started having blood appear when I go to the toilet, it has been like a week now, but in the last couple of days it has become more frequent and bloody looking. I suffer with anxiety generally and to be honest I have been great in regards to that for a long time. But, this has me worried. When I worry it is like I lock up physically and become stiff stressed and then start to worry every little thing is due to something being wrong. I run two businesses and also work social services, being busy actually keeps me happy but this already feels like it might be stopping me in my tracks. I don’t know.
