Just from reading this, it sounds like you are most certainly there for them!! You care, and that's the most important thing. I'm sure they know. 
Thank you (: I try to be there for her, but I don't feel like I am
It's no problem. Has she read your poem?
Has she read your poem?Yeah (:
Good good, in that case I'm positive she knows that you're there for her, even if you feel like you're not.
