Im sorry, that sounds like a terrible thing to have gone through. I guess just take one day at a time. Do you journal? It might help you to sort out some of your feelings. One thing that I did was to write letters. I never sent any of them, I would take them down to the beach and burn them.
You dont ever have to apologize for being low on here, we have all been there at least once.
A lot of people also exercise, the physical activity and endorphins are really good for you. Most importantly, remember to take care of yourself, eat and sleep!
I guess I gave the wrong finger to the wrong man...
