In a sense, I'm the one who ruined me: I did it myself.

“There’s a corner of my heart that is yours. And I don’t mean for now, or until I’ve found somebody else, I mean forever. I mean to say that whether I fall in love a thousand times over or once or never again, there’ll always be a small quiet place in my heart that belongs only to you.”

Fact is, not everyone is going to like you. There will be instances in life where friendships cannot be forged and you will be loathed or rejected without reason or cause. Let it go and move on. Some fights just aren't worth the time or effort. Invest your energy where it's wanted.
