It feels that way right now because everything is fresh. Take your time and think about the happy times you spent with them and understand that while everyone loses people around them that everyone process the experience differently and while some can handle it calmly on the outside they hurt too. Be there for other family members. Take time for yourself to do something that will refresh you. A walk perhaps or going to a movie? Give yourself the permission to not be okay to cry or to laugh at someones joke. Because life is mysterious, wonderful, sad, hilarious, crushing and ever changing. Just know that life will change and be okay to change with it when you least expect it. Most of all take care.
