So I was in the military for a few years, spent a few years deployed and had absolutely no problem.

I was not in combat every day, but played a direct part in conducting drone strikes on an almost daily basis while over seas.

I don't have PTSD, I don't get afraid of loud noises, don't have anger issues, never been shot at etc...

What I do have is an excessive guilt that seems to be getting worse all the time, especially in the last few months, I'm becoming very depressed, I can't focus on anything during the day and I have been stuck in this loop of thinking about what a piece of crap I am even though I know that the people I was helping to get rid of were literally selling other people on the street.

Does anyone know what this is called?
