Becky,
Wow, can you believe it? 30 already! Time really flies I guess. I hope all your dreams have come true by now. Right now (18 year old you) I have tons of plans for you by the time you are 30. This is where I hope you are: I hope you are married to a wonderful man named Matt and have two children by now, I hope you are working for NASA and on your way to becoming an astronaut, and I hope you are having a wonderful and successful life. If any of those things aren't true, don't fret. There's nothing wrong with you. Your time will come and everything will work out in the end. Just remember, "believe in yourself."
I would like to apologize for something. I'm sorry you don't have a very good relationship with your parents, especially your mom. I've never been able to talk to them about some things and I wish I would have given them a chance. I hope you can get past that and start to build the great relationship that you could have. Also, I'm sorry for not getting along with our sister. I know she was weird and kind of dorky, but that's who she is. Even though she is very different from you, that doesn't mean that would can't be friends. If you haven't already, make amends with her. Forgive all the dumb and mean things she has done to you and become the sisters you are supposed to be.
Well that's about all I can say for now. May all of our dreams come true one day. And if they don't, don't worry too much. Everything that is meant to be will happen. Don't be afraid to make big changes in your life. Take time to slow down from your busy life and just stop and smell the roses. Don't worry about the little things in life that don't really matter. Most importantly, have fun. Life is all about having fun. Do what you love and love what you do.

Good luck!!!!
Becky
