It's totally normal don't worry, your brain is preoccupied with other more important things. It's going to take a while for things to feel anything near normal again and doing even little things like vaccuming is going to be weird. I don't think there is a right or wrong way to be acting through things like this. Just take every minute as it comes with one step at a time. Don't beat yourself up about not being there. We are always very good at torturing ourselves with what if's and should of's, when really it probably wouldn't have changed a thing. (i should listen to my own advice!) Do you mind me asking what happened?
