This is so true. At our time of life we expect to lose people that we are close to. I lost all my immediate family (mother, father and brother) by the time I was 32, now it is extended family I worry for.
It takes such a long time to pick yourself up and see a way forward but it does happen eventually. You never "get over" losing someone, anyone that says you do is either fooling themselves or has never lost anyone they truly love but the pain of that loss is easier to cope with as the years go by. You suddenly find yourself able to think of them without crying uncontrollably, even smiling sometimes as you think of a moment in history when you were enjoying something together.
So to everyone that has lost someone close to them, share your memories and thoughts, it does help eventually.
Always know that you will carry that person with you in your very being throughout your life and I truly believe that they are always there for you, watching over you from a better place.
Take care of yourself and those you love.
