Pre-Meeting Fears

Hello. I am so confused right now. I am meeting my foster mom tomorrow. I had contacted her about a month ago and she said she wanted to meet. At first, I was EXSTATIC! Now, I am PETRIFIED. I was actually thinking about cancelling. Why? The reason in a nutshell: When we talked she said I was such a beautiful baby. Well now I am ugly and fat and dont want her to regret asking to see me after all these years. I also dont want her to lose the "beautiful" image of me and after tomorrow she will. Not to mention, she has invited her other children as well tomorrow so there is going to be a LOT of people. I feel like I am from the scene in Antwone Fisher when he reunites with his family. I am VERY shy when I dont know someone and ESPECIALLY with that many people around. Not to mention she is making dinner and I HATE eating in front of people, especially those I dont know and I am so self-concious of my weight as it is. I dont know what to do! I want to cancel SO BAD. She called me today to give me directions and she said again how excited she was to meet me. She will SURE regret that tomorrow. Argh. I dont know. I was thinking about bringing her some poems I wrote about my birth mother that have actually been published but I'm not sure if thats a good idea. Another thing is I have wanted to meet my foster mother and my birth mother for SO LONG. In a way I felt kinda safe that I would never meet either of them. Now this day is here I dont want it to be. My foster mother doesnt have any info about my birth mother and she only had me for 6 months so how much is there to say? What if they dont like me? What if I dont talk much? What if it turns out to be a horrible experience? If anyone has any advice it would be GREATLY appreciated. Thanks, Jen
