I take the emotions how they come,i don't listen to those advice "It is well,let him go,they'll not be happy to see you like this,it gets easy by time,be strong,it'll come to pass ".Nobody knows what your loss means to you,no one can ever be in your shoes,every loss is different to everyone even if you're in the same family,it hits differently.For me ,I cry when i get overwhelmed,i talk to him as if he is with me,i send him messages.It's the hardest thing to deal with but i'd suggest you just be yourself,take it how it comes,don't play strong,don't hide your emotions.Mind sharing more about your grief?
