Can I emotionally handle adopting?

Since I placed my baby girl, my life has changed so much. I am now at a point where I can see myself having a stable family of my own. I love adoption, and would really like to adopt some day. I feel like I could empathize with my child's birth mother and have a really great open adoption. But I am worried that it would bring up too much grief and trauma and that I would be unable to bond with the baby because I truly understand the heartbreak of the biological mother. I also worry that my birth daughter would resent me placing her and adopting another. I don't want her to feel unwanted or like it's unfair. Any thoughts on this?
