Is it love or my personality disorder?

I think I have a skewed idea of what love should look like. Years of awful romance movies and fairytales have lead me to believe love is life altering, feel it in your gut, toe curling waves of big emotions. But what if that's just my borderline personality disorder? The big feels for the unattainable men? What if love is quieter? What if love needs to grow? What if what I thought was love, was actually just my disease? How do I know?
