Oh honey, i don't know exactly what happened, but what ever this is, if you feel that bad, it is prolly not your fault.
i have felt like i have been to blame too, but actullay, there was absolutly nothing i could have done to stop what had happened,
grief is one of the steps in alot of things, it is hard to deal with, but remember this, it wasn't your fault, if you need someone to talk to just Pm me. i'll be there for you
much love,
JUlie
