golf mom, Each person's healing time is different. You are in mourning and yes, you are overwhelmed w/all that has transpired. It will take you some time to get your footing again, but you are well on the way of doing so.
Setting up a tennis match is a start. Take each day as it comes and do not look too far into the future. Gardening can soothe the soul and it sounds like you've been busy planting flowers, etc. Work through the pain and know that you will become stronger for doing so.
Give yourself a break...you've had a rough year or so and it's going to take some time for your interests and hobbies to matter once again. Trust me, they will. Your focus has been on your h for a long time and his behavior and that will take the wind out of our sails because it's exhausting and frustrating dealing w/MLC each and every day, minute by minute. Once the dust settles and life begins anew, the world will look different and you will find that life is waiting for you w/open arms.
Golf Mom, you are right where you are suppose to be at this time. Keep the focus on you and your family.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
