Angela,
Well, many women stay 29 for years....look at it that way. No birthday, no aging.
Not to make light of your situation. But sometimes we have to laugh so we don't spend all our time crying.
I don't think that people intentionally hurt us or neglect us, I think it just happens. But I bet there are many people who love and care about you, that you don't even know about. There are people in our lives, that admire us, love us, and think about us- and we don't know it. You may not know, but there was someone somewhere that thought about you on your birthday. Someone else who considered calling you or sending you a card, but something happened so they couldn't.
I know from experience that telling you be happy because you have your children, or be happy for this or that that is in your life, is not going to help. I have found myself iritated by such comments, when I am so sad that I don't want to continue, telling me that I have children who need me, or that I have a good job or a great education, doesn't help. We are always told to count our blessings. But sometimes we need to acknowledge our pain. Too often we discount ourself, saying we have no right to be sad. But you have every right to be sad, Angela. It was a sad thing that happened.
It seems ironic that I would even give any advice to someone with what has recently happened and is happening to me. But I find I can offer advice, but I cannot figure what to do for myself. "Doctor heal thyself" never works.
Take care. And a belated "happy birthday".
You are loved.
