Yes - your dad will have the hardest blow for now, I truly hope you all can be supportive of each other.

I'm glad to hear you're okay, and whatever comes your way in the form of feelings or maybe even the idea of 'I have peace with it', it's all okay, just take the time to observe/feel whatever there is. Might come soon, might come later than you expect. Sometimes the first time we don't really realize what's happening.

Anyway, stay strong.
