Hey, there girl! you need to move on.
Do not follow what you have been negatively told by your parents who have adopted you. It is your choice to give importance to certain things and ignore the rest. I don't want you to feel depressed if you want to go into this field of motherhood. First, of all, try to stay positive. Keep past behind, because what has happened now could not be changed. So you need to move on, rather than just thinking about the past. Surrogacy is a beautiful option. You can go for it and try to find this clinic in Europe, rather than other random clinics. I will definitely handle all your issues and situations.
Take care and stay happy!
