Condolences to you & your other family members over your loss Julien.
Myself, I wasn't close to my Father when he passed in 2001, nor am I close to my Mother at all, but I'm sure your loss is much deeper than I can imagine - especially if one is close to their family members.
With all the words of 'staying strong' & 'be strong', I just want to add that it's quite ok to have a moment of weakness here & there too.
Be weak for a few moments - break down and let it out a few times. It would be unnatural not to.
After all, we wouldn't know strength, if we didn't have something to measure it against.
Best wishes Julien,
James
