Wedding

I am participating in my cousin's wedding this weekend. I wasn't initially, because I wasn't asked to participate because I would not be able to afford to buy the neccessary items to participate. Then, my aunt scolded my cousin about including all of our other cousins in the wedding and not including me, so I was added as a bridesmaid. My aunt and uncle voluntarily decided to pay for my bridesmaid dress under the stipulation that I pay for everything else (i.e. hotel, trip there, food, hair, nails, etc.) myself. So, not only am I unwillingly participating in this (because I was fine not being apart of the wedding), I am going broke doing it. I recently bought a car, a '98 BMW, and that took $2600 (but my uncle paid the other $1900, so I can't complain). But after doing that and buying my son and boyfriend suits for the wedding - not to mention their haircuts and shoes - and getting my dress taken in (because it was waaayyy too big) I only have about $200 left. And that has to go to the hotel and gas for when I go there (Harahan, LA). My electricity bill is still due ($113) and I need to get groceries.
I am doing all of this alone. My boyfriend doesn't have a job nor does he have any money. The financial responsibility is all mine and I am sick of it. I was actually planning to use my refund to get my son and I our own apartment, without his father, but so many other expenses have come up that I just don't have the money to do it. And on top of all that, my son's birthday is coming up (October 24th) and I need money to do something special for him. Then, Halloween is a week after that. What's a girl to do???
