Is there a way to actually shorten the life span of my mother? I have been taking care of her for close to 19 years. This can't go on.

I do not need to go over the nitty gritty of the details. She has alz but all other vital signs are normal. Granting nothing catastrophic or cataclysmic will happen, my mom might linger on and heave her entire care to me for another 10 or more years. I have paid and still paying heavily in terms of lost income, unemployment, lost opportunity not to mention no wedding ring or even a serious boyfriend or even just the time to have a meaningful relationship and been stuck postponing my plans, my own life, my own dreams and ambitions. I worry in the next 1 to 2 years she will eat up all the resources I intend for my own daughter who will be moving soon in the next 2 years to high school. Last night i searched the internet for any medicine that might do the job. Any ideas? I just hope the meds are available in my country (I'm not in the US). If Mother Nature won't do her job on my mom, I have to do it myself. This cant go on for another 5 or 10 years. I myself turning 40 this 2011 I also must save for my own retirement and my own sanity. With mom possibly alive for the next decade, how in the world will I save for my self while sustaining me, my daughter and my mom. I have been officially unemployed for 6 months this December. Any drugs or meds to do the job? I don't have a car to do the CO2.
