it becomes very painful on days like mother’s day when the girl’s are spending time with their mother and making her mother’s day cards etc and I’m not really included
you are not included because you are not their mother
This fostering process is my pregnancy. This is my only shot at having a child of my own who can call me mom
foster children don't call you mum.
she won’t listen to reason and even after she calms down and seems okay with everything.
to be honest, I think you are the one who won't listen to reason. Your step daughter seems to have a far more realistic understanding of fostering than you do.
Of course it will impact on her hugely.
I am a foster carer, and I think you have very unrealistic expectations of fostering. The child does not become yours, ever. Even if you get special guardianship, the child is not yours. Fostering is massively disruptive to a family.
Fostering is best regarded as a career, it can be an amazing thing to do, but you have to keep in mind that you are doing a job, and have no right to expect anything back from your "customer" - not love, not communication, not appreciation, nothing. Of course sometimes you do, but it is your job to love and expect nothing in return. So similar to step parenting in that respect, except far more so.
I also think your diabetes will be as much of an issue with fostering as it would be with having your own child.
I am very sorry you can't have children. Maybe you would be a brilliant foster carer, and make a huge difference to the lives of many children, but your step daughter is right, now is not the time for that, very unfair on the children already in the family, if they are frightened by the prospect
