Please help me, I'm so hurt!!!!!

Hey I have a question for you all. A few months ago my cousin died of an overdose, then my auntie killed herself a while after that. Now my brother right now is dieing of cancer, and I'm currently dating a wonderful girl named sam. I've been with her for a good 10 months, and I love her so much. Everything about her takes my breath away. And I'm pretty sure she loves me too, but for some reason she's never here for me. She either makes plans with me then brakes them for others, or just plain out ditches me. I've told her time after time how much I need her, I'm so depressed and she makes it worse. Each time she promises me she will. And she's not doing it, a few days ago I told her again and it sounded like she will actually change now and suport me, but I've only seen her for 2 hours since then. What should I do? I can't picture life without her at all. I can't picture me with another person, I love her so much all I want is for her to be here for me :'( Tweet
