Wondering if anyone else has this..

I know it is OCD ultimately, but still I'm having issues with taking a past event where I felt I did something wrong and slowly escalating the 'what if' regarding it to the point where 'what if X happened and I'm a terrible person.'
I start worrying that 'what if' the absolute worst case scenario of this were true would I be a terrible person and not deserve to live.


My OCD can be truly menacing at times.
