Its so hard when you feel like everyone around you is pregnant. I wanted children but can't have any because of my disability and I get so envious of others who can just have a child without all the angst I feel around it.
But I have decided that life is wasted on regrets. Ok I couldn't have what I wanted, but I do have a lovely dh, a nice house, hobbies and I can sleep 9h a night and prioritise myself and my health.
I think you need to make the decision to accept it and let it go. I'm not saying it's easy at all, but maybe speak to a therapist or someone about it who can help you come to peace with it all?
Good luck op, it's awful and horrible. I am met with suspicion by many people for not having kids, and people always ask me about kids without realising what a painful subject it is for me. I wish people would realise it's not always easy for everyone.
What about your step children? Can you become more involved in their lives?
Remember your worth isn't based on whether you have kids at all. As a society we treat childless women appallingly but I think you need to find a way to realise your own worth is down to yourself instead of expecting it to come externally. If you're at peace with yourself, nobody can touch that.
Therapy had been invaluable to me and I really recommend it. That or read about childless women who have done other amazing things, like Dolly Parton, or Jo Frost(supernanny)! They are both absolute icons from their own achievements and the fact they don't have children is irrelevant.
Anyone who thinks you're a failure of a woman for not reproducing is a misogynist, narrow minded idiot who you don't need in your life.
You've got this!!
