I am so glad to hear you sounding strong and positive. I am glad that you and your son are able to spend so much time with your family. That is wonderful for all of you.
As for your anniversary, it sounds like you have a good handle on things, but do not hesitate to reach out to people here or in the alt. if you have feelings crop up that yu would like to discuss or if it turns out you would just like to have some support.
