I'm afraid of heights, but if you were on the balcony of a 60 story building ready to jump at 3am, I'd sit with you until the sun set again listening to your life story.
I'm afraid of sharp objects, they make me think of my past, but if you held a blade to your skin, crying in the shower,  I'd barge in and hold you until the water got cold, soaking into my clothes.
I avoid dark alleys and walks at night, but if I woke up without you next to me,  I'd wander the city looking for the trail that would lead you home.
Depression isn't new to me, I'm familiar with how distorted reality gets and how hard it is to hold on. I'll tie a rope from my heart to yours, so one of us is always there to pull the other back.
