The pain will change, hopefully become less raw with time and in distance allow perspective impossible now. For now, care for yourself, those around you and be as kind and patient as you can. This is the best life advice I have to give.
"Missing someone isn't about how long it has been since you've seen them or the amount of time since you've talked. It's about that very moment when you're doing something and wishing they were right there with you." This is so true.
