People will tell you anything when they're angry, but they say it just because they know it'll hurt you. It's like that quote; "It's hard when the only one who can make you feel better is the one who made you cry" or something along the lines of that.
I'm really sorry. I'm always here if you want to talk, love.
I'm so so so sorry, my father left too, and his gf would scream at me calling me fat and ugly, until he finally moved far away, and I get it with your great grandma, my grandpa was pretty much the same way, he raised my family, and when he died my world fell apart, listen If ya ever Wana talk just message me and ask for my cell # I'm always here hon!
Oh, hunny, I'm so sorry to hear all of this heartbreak :( Your dad doesn't deserve being your father; you're a great person, who's loved by everyone who knows her. And your grandma very well loved and wanted you and your dad is a cold, heartless bastard if he tells you these things. You know you can always talk to me if you need to <3
Hah yeah, he really, really is
