Mine is kinda dark, but.... my biggest fear is being tortured and tormented against my will with no way to stop it and no help.
For real, its a terrifying idea, I mean that would be the worst possible thing that could happen to a person. And theres always the possibility it could happen, it does everyday.
I dont like live in actual fear of this every day, of course. I mean I have faced torment before. And it was awful. But I dont live in perpetual fear of it happening. But if I were to share what my biggest fear is, then yeah, its that. It would be the worst possible thing to happen to a person.
I dont think its so awful to have this fear, though. It helps me remember to focus on things that matter. Where as in my old life, I was sad about all kinds of meaningless things, now I feel happy as long as I have peace of mind. Its all I really strive for, for the most part : p
