Hi sorry just came upon ur thread whilst resting while my LO sleeps (!)..
I also suffered Infertility for many years, did Ivf finally got pregnant at 42! So I completely understand the complexities of being infertile and the stigma attached... I have no experience with adoption, but just wanted to congratulate you.
You have every right to feel excited...
It may be that you are too scared to feel excited in case it gets taken away from you so u might actualy just be doing a bit of self sabotage there with your worries, which is complete normal under the circumstances.
My LO is turning 1 next week, and I feel I can finally let go of the fear that of him dying...he may actually survive! (because of Ivf I had fears he wld not be around forever, he is the most photographed baby on the planet!!!... Just in case...) it's irrational but understand why I feel like that. I may actually be able to fully celebrate him being here now without that shadow of doubt which is just me preparing myself 'just in case'!
You obviously have a very complicated family situation. I do too in a different way, my OH has 3daughters, now all teenagers from previous marriage. The girls mum is a complete crazy lady with no coping skills, emotional maturity of a 12yr old etc etc, verbally abusive, controlling, narcissistic etc has majorly emotionally abused her kids in so many ways.
2of them have been completely destroyed by her behaviour, and they have paid for it in social consequences (can't even go in to it too tragic for words).. But I wanted to say, me having a baby has really helped unify us as a family. I waited for a very long time because I knew the youngest wld find it very difficult to adjust, but aft we had yet another tragedy with the girls, i decided then and there it was my turn to choose some thing good for my life, instead of worrying always about the girls needs whilei felt empty. Because I couldn't control what happened in their life no matter how hard I tried.
Having our bub has been a real blessing, and the girls love him and it has given them new meaning in life. Sorry about the rave, Hope it makes sense, but just wanted to give u hope that t may not be as bad as u think. Our lives will never be normal, so we have to make the best of our situation, sometimes it's unreal, other times it's awful, but it's our life and defines us in all ways.
All the very best to you, I'm sure you are strong enough and it will be rewarding. Just make sure you get lots of support from whoever is supportive and keep away from those who aren't. U may be quite surprised at the people u thought wldnt be supportive are often thrones who are and shockingly the ones u thought u could rely on u actually can't!
Fate has a funny way of leading you in directions u never dreamed of, make the most of it if you dare. Sending you positive vibes!
