Oh Robin, I am so shook up reading this. Your almost ex is ONE person! There are so many who know what a beautiful person you are! So many people who need you here. Your son is young, maybe not able to understand why you are acting like 'this'. Maybe can't deal with it.
We all love you and need you here, as do your girls. It will get better, it will take time. Please hang on. I'm keeping you in my prayers. {{{hugs}}}
