What is your biggest fear?

[mysticwolf]

I used to be scared of heights when I was little, but that fear has mostly gone away.

Some things I fear now are:
Not keeping my promises, and therefore disappointing people.
Not fulfilling what is expected of me (namely the academic expectations set by my parents)

I am a romantic; I often daydream about the perfect relationship. I eat up the romantic subplots in young adult novels (things like Divergent, Hunger Games, Legend, Enclave, etc). I worry about screwing up a relationship; I worry that I might not be a good boyfriend, because I don't have much experience being a boyfriend. I know that I'll be able to get into a good relationship, but I worry that I'd do something to mess it up. Not infidelity, I would never do that, but I just worry that I wouldn't be a good boyfriend because I don't know how to be a good boyfriend. That's probably my biggest fear: That I won't have the perfect relationship.
