First of all you're not going to offend anyone here...we've all been through or are going through the adoption/foster process and have all asked questions.
Our first birthmother was about your age and had made up her mind and refused to let anyone change it. Her mom and grandma were against her adoption plan but she knew what she wanted and stood strong in her decision. She said she always knew Josy wasn't meant to be hers and that she wanted what she felt was best for her, not what anyone else thought was best. Our second birthmother was younger, she thought she wanted to make an adoption plan and did. We met her and moved forward in the adoption process but once the baby was born her mom and grandma easily changed her mind and she decided to parent. Whatever you decide has to be YOUR decision...you know what is best for you and your baby.
Good luck in whatever you decide.
