I'm glad to read that things are moving along nicely for you and your son. People are seeing that you are really happy and that tells me that you've been under a lot of stress in the past year or so. You are healing and w/healing comes life, smiles and new adventures.
Your flowers and activities that you have planned for your garden/yard sound great and the fruits of your labor will bring forth many happy and beautiful flowers very soon. I'm glad you've got a lot of fun things to do as well as some "must do" items. Balancing your time and activities helps and yes, you are going to have ups and downs for a while.
I'm happy to see that w/him out of the house, you aren't focusing as much on him. This helps you stay focused on you, your life and your son's life.
Spring means new beginnings and I think you are well on your way. Keep up the good work!
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.
