I Call This the Heebie Jeebies

I am so excited right now I can't think!  But at the same time I feel bad, because what I am excited about, some of my friends can't come with me.  But I still really wanna go and am very excited, I just don't know what I'll say when I see them again, and they give me that crushed look because they couldn't come...I call this the heebie jeebies, because I am happy and excited but also feel weird hehe.
