Everything assumes a different intensity when you are feeling the pain of loss. Be prepared. A minor annoyance that you might once have managed with a shrug now becomes a nuclear crisis! You are no doubt going to do things perfectly imperfectly. That is part of our path as humans. Forget about striving for perfection while dealing with grief! If you beat yourself up every time you forget something, have a breakdown, or don't do something correctly then you're going to end up very black and blue. I guarantee you won't want to look in the mirror! So be kinder and more patient with yourself.
