Ive always thought this. THIS is heaven. THIS all we truly have that is promised in each moment, each moment may be all we have. Sobering thought. All the happy memories, the things you wanted, the love of your life.
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.
