I struggle to finish story-heavy games

I'm not sure why exactly, but I just struggle to finish basically any game where there is a heavy focus on story.

I seem to get about 90% of the way through them and then just stop playing abruptly. I think sometimes I do that because I just play too much in too short of a time, so I burn myself out on it unintentionally because I'm just enjoying the story so much up to that point. Other times I seem to be able to tell where the story is going and I don't like it, usually because it's tragic and I don't want to experience the tragedy I know is coming; It's like this sense of dread overcomes me and I struggle to continue. Other times still, I seem to just know the end is coming and I don't want it to end so I put it off and then forget that I was almost done with it.

Does anyone else do this? I feel bad for having not finished a ton of different games, even the ones I was really enjoying at one time.
