Is it dumb to plan your own bridal shower??

I'm 20 and getting married in the end of January. All of my friends are off to college and I dont really have any close relatives. My sister lives 9 hours away from me and I doubt my mom would throw me one. My sister just got married and I threw her one, my church threw her one, her husbands church threw her one, and her mother in law & aunts in law threw her one. I dont mean to have a pity party but.. seriously... no one is going to throw a bridal party for me. I think that is really depressing and sad!! I know its not the focal point of getting married... but wouldnt that make you sad? So how tacky would it be if I lined one up? I don't know how much I like the idea of doing that but uhhhh.... I just wish I had family that cared about me... what do you think?
