Throwing your own bachelorette party

Is throwing your own bp seriously considered rude? If so, why? I am completely baffled by the responses I seen when I looked this up. In all honesty it looks like I will be in that boat since all of my bm's have been completely uninvolved with anything, that goes for my family too. I've been alone for this entire process which is another issue in itself... Maybe that isn't even the real issue I want to pose... Weddings are suppose to be a happy time right? Honestly this whole thing has just been hurtful and stressful.. I know you're suppose to focus on your life with your mate and the union of marriage but it still hurts to see how your family and friends could care less. I'm having a real hard time with all this...
