Despite the BS that flies around here, we are all a family of sorts, and are all sending support and prayers to you. Please don't hold back at the funeral, wake, and other times right now, although I know you feel like you have to hold it together. Take some time to let it all out, and really mourn the passing of what is obviously someone incredibly important to you.
Please take care of yourself and the others around you. Sincere condolences to you.
