The annoying and even bad things that happen in your life aren't exactly directed personally to you.
A negative person who wants to hurt you doesn't have a special agenda where he or she makes it their life purpose to make you miserable. They're just miserable.
A negative, random event that came upon you wasn't specially constructed by the universe (or God, if you're religious) to test you either.
It is your life, but it's just that, life.
Don't take everything so personally. That's just the recipe for misery. Just focus on what would make you happy instead.
