Hi Middlechild. I am also a middle, but I don't think it has anything to do with the way I was treated, and still am. I'm in my mid 50s and I have learned to just ignore the fact that I can't do anything right and my sister can't do anything wrong. It's just my dad's opinion, after all. I know who I am and what my good qualities are, and my faults, and nothing and no one is ever going to make me feel bad about who I am. I do get upset at times and get depressed, but it's not about how anyone thinks of me (at my age I don't give a hoot), it's about being in a negative atmosphere.

I hope you can learn to cope with it. You will never change them. You can only change how you deal with it. Don't internalize the negative things. It might help to write your feelings about it, and make a list of the good things about you. Try to add to the list frequently. Keep it with you and refer to it when you feel your self confidence slipping. And try not to worry about being accepted by your parents. Just be the best you that you can be and be happy with you!
