Awkward 12-year-old Tries to be Wise

I am often confronted with my younger friends' problems.
That's okay, to an extent, because they're like my little sisters, sort of.
But I'll talk to them over text, and I'll send back a heartfelt, attempt-at-counseling and hopefully encouraging text, full of words and thoughts and prayers and even hugs, and then, after a few minutes, I'll receive back one word: yeah. Or worse, "haha yeah". Then I just get ticked at the person I'm supposed to be bearing up. Do any other adult-o-lesecents feel that their help is wanted, yet seemingly scorned?
