I hope you are adjusting by now. I remember that my 50th birthday was the first one that really "hit" me! For the first time, I, too, really felt like I was starting to get older. Well, now I am in my early 70s and realize, looking back, that the 50s were still a good decade. In fact, between me and you (LOL) I met a guy when I was 51 who was 10 years younger and we dated for some time. So there is still a lot of life left. Happy Birthday!!!
