My pride is KILLING me?

I think I care to much about what people think for the sole reason that I don't want to be seen like I’m below them. I hate being put into positions that show me as inferior or like a peasant in a sense. Here’s an example: I am graduating high school very soon and my family wants to do something after the ceremony, but I would just rather not do anything, or just go out to eat. Why? Well my family is small, so we would just go to my sisters, like what the five of us!!! F that, just thinking about it makes me upset. Or maybe I just don’t want the attention on me, that scares me to. So why don’t I want to go to my sister’s after I graduate for a simple small get together?? That’s the friggen question.
