I am retarded

Ok, so I had a nice little surprise this morning when I found out that I am now off work on Thursday and Friday (yeah) but I still get paid (double yeah). So, I decide to be a good daughter (1st mistake) and call my mom to tell her that I am off and will be available for contact on Friday (my great aunt is having major surgery and my being unavailable was causing my mom a lot of undue stress).
Well, didn't I just open up a can of worms.
See, my mom has been having back and knee problems for the last month or so and she finally went in two weeks ago and had an epidural to relieve the pain. Well, that lasted all of a week and now her back is "killing her" again and she can "hardly get around." (Can you feel the guilt yet?) So, her doctor wants her to have the procedure (in my mom's twisted brain, surgery) again. Last time her sweet next door neighbor drove her to and from the HOUR LONG BASICALLY A BIG FUCKING SHOT procedure. However, my mom, being my mom, stressed her neighbor out so much over this that they both had to take to their beds for TWO DAYS!!!! (an epidural is a shot people)
Now, my mom, again being my mom, wants me to fly to fucking Tennessee on Wednesday afternoon so that I can then drive her to and from her "surgery" on Thursday. Now, I know that I have a unique situation in that I can fly for free, however, that doesn't change the fact that I have to work on Wednesday morning after which I would then have to get on another airplane fly to fucking Atlanta (aka HELL) and then wait for another fucking flight to Knoxville. All so I can get up at the butt crack of dawn the next day to drive her 5 miles to get a FUCKING SHOT in her back!!!!
Why am I an only fucking child?
If anyone is reading this, do not just have one child. Have multiples, give your children back-ups, support, help. Don't punish them by setting them up for a life time of guilt and solitary servitude to you.
I must now figure out how to grow my own back bone and tell my "poor sweet mother who is all alone" that I am in fact a worthless daughter and that she needs to call a cab.
I hate my life.
