I've known this girl now for 3 years and last saw her 6 and a half months ago. She's not actually my girlfriend, but I said that I will ask her out next time I see her. She's absolutely ridiculously shy and I love her more than anything in the world. She loves me the same amount and I trust her. She's 15 and I'm 16 nearly 17 in a couple of weeks. She told me that she cut herself a couple of weeks ago and she's not an emo. She's really nice , but when trying to help her she's not very responsive on Facebook, phone etc. if I could see her again I would help her, I've had a girlfriend like this before. Her family hates her and she only cares about me and her dog , but she is too shy and doesn't want to come out because she doesn't know what to say to me , she doesn't want to things up between us... Last time I saw her , we hardly talked but it was nice because I like it when she's shy, she's very cute. I text her everyday and sometimes get a reply, I'm planning on seeing her on New Year's Eve but shell probably come up with an excuse not to come out, like she's at her family party or something. She doesn't get on very well at school and all I know is she only has two friends , she's sick of them and can't be bothered with them at the moment, she's not a big weirdo and acts like a freak. She's the most amazing person in the world , she means the world to me. I want to know what I can say to her when I meet her.. Thank you please help!

Here's a text of her explaining some things... Please help and don't be stupid on your comments...
I've blocked there names for obvious reasons

About me, my family say things like that to me. I have nobody to talk to, cause friend 1 and friend 2 just do my ing head in all of the time. But I have you which is all I need, well and my dog obviously ha. But Yeah, you won't believe how many times I've attempted to kill myself and nobody even knows about it, apart from you now. Because you're the only person who makes me feel like I'm worth something, sorry for ranting. I'll stop. Xxxxxxxxxxxxxxxxxxxxx <3...

Oh another reason why I don't come out, I am physically and emotionally exhausted. And I'm at the point now where I have to force myself to eat, because I am completely off food and it makes me feel ill. Another thing ed up by stupid depression that affects like everything. Right sorry ill stop now, just thought I'd explain myself...

This is the most I've ever got out her, she never comes out the house , and when she does its because her family make her...
I usually get one sentence replies... Help ?
