Hello brokenheart1! ( I love your username, it's so aesthetically pleasing. )
The kind of primary source document that I find most interesting to analyze are diaries, because I like to see someone's perspective on a subject or time period. It can be quite interesting and gives me a first hand look on a matter through someone else's eyes and opinions.
I hoped that helped, I always enjoy getting brainliest when possible!
