Continuous depression. May come, etc)

In January 2021, I had anal fissure and mucus started to appear in stool. I was scared of going to bathroom due to regular severe pain. When it didn't heal for 1.5 months, GI doctor did many tests to rule out IBD but reports were OK. Everyday I was waiting for reports, scared of bad results, I thought I had dangerous disease and I'm not gonna survive. In this period some times fissure healed and reopened, it became chronic and Dr suggested surgery. I didn't go for surgery and fissure almost healed now but terror is still there in my mind. I'm unable to come out of this. Please help me what should I do now. Everyday I shiver before going to bathroom (fissure may reopened, mucus may come, blood may come, etc)
