It is human, all too human. Sometimes we fall apart and when we fear we are falling apart we have already fallen. There is no comfortable place, people don''t understand as if they forgot their fallen periods. When we fall it is like it never happened before. There is strength deep inside but we can't reach it. We are fearing something that has already happened. Time, we need time, patience. We need to accept the grief. Grief, grief... That will also pass.
