Feeling bad.....horrible actually!

I don't like feeling bad about things and maybe if I vent them here I won't feel so bad. If you read my previous post then you know whats going on. I am feeling horrible about it, physically sick in fact. I hate knowing that I may have contributed to the fight without even knowing it. I don't want anyone thinking that I would purposely say or do anything to keep 2 sisters from being friends. I feel they are both important to each other and need to be in each other's lives. I won't apologize for what I said here because neither of them will ever read this. I have apologized individually to them and hopefully they will accept it. It is making me sick to my stomach to know that things were on the road to recovery and then all because of comments I made on Facebook to no individual in particular have derailed things. If they choose not to accept it then what can I do. They know me and know that I meant what I said when I apologized. Talking about it, even if it is in blog form is helping me get it out. Thanks for listening/reading.
