Meeting my blind date Sat. and I'm nervous?

Right now, I have a series of what ifs going on in my mind. Like, what if meet and my blind date meet and he's not what I'm expecting and I get disappointed or what if we meet and I'm not what he's expecting or what if we meet and everything goes well, but I have an embarrassing moment and I feel bad or what if ...I don't know any more what ifs, but I do know one thing and that is, this guy sounds wonderful on the phone and we've been talking for about a week getting to know each other. I don't want to feel disappointed on Sat. at all for no reason despite how this guy looks. He sounds so wonderful you guys and I def. don't want to hurt his feelings for no reason. Deep down inside, I think everything will be ok, but I just feel so nervous and scared all together. Idc about his looks; it's just that I want everything to be so well and good on Sat. and I don't want anything bad to happen to cause us to go our separate ways and remain friends; I want it to be more. Like I said, this guy seems like a wonderful person despite I have no idea how he looks.
