Welcome to hell again

so got a call from dad last night. he and mom left 2 days ago for vacation in Idaho. but anyway he called to tell us mom fell and broke her leg again... AGAIN! i was so mad that i honestly almost threw up i told him there was no way in hell i was helping her out again. not after the last time she broke it. it has been almost exactly 4 years and i have hated her almost every day since she fell the first time. in the past 4 yrs most of my almost a thousand cuts has been from the stress she has caused in my life. i dont know if i can make it through it again.
