I'm sorry to hear this is happening and you're so confused.
I can understand even after everything you still want the love and acceptance of your family.
If your family show no interest or desire to make things up to you and have a relationship with you (not that they 'deserve' it but it would be up to you whether you wanted it) then it truly is their loss.
You didn't get what you needed from your family but you have a new family now (your little boy) who love you and need you, I hope you can find positves in that.
