What have I done?

I think I've upset Sharlet beyond belief yesterday...well, earlier. She was asking that if she were to kill herself (which she wont), would I just move on? I got upset, and she left upset...maybe a little angry. She's not talking to me at all now it seems. Have I blown things getting upset when she asked me not to get upset? What can I do? I...I hope she's ok. I dunno what the hell I can do! FUCK! I need her...I need her more than anything. God dammit!
