Venting my little ... off...

I wish that my mind could rest, but I am too upset. 
I am upset at the nursing home that has mistreated my mother, and the other nursing home, as well, because they have both drained my mother of money until she is deserately broke, and dependent upon others.
I am upset with the girl for not cooperating, causing insertion into the medical/psychiatric disaster that is "care" in this state, as well as in many others. I have worked hard to keep her out of their clutches, as being in their "care" is sure to ruin the entirety of her life, but she cornered me, blindsided me, and I had no choice but to insert her into the hospital.
I am upset with that hospital, because they addicted her to a dangerous medication they set her free, unable to get any more of the medication. for the 2nd time in 6 months I am faced with having to wean her off medication in order to minimize the withdrawal. 
I am upset with my mother, both of my brothers, and my older daughter, who is not "there for me", because she has passed judgement upon me and I have failed.
I am upset with myself, for letting all of it bother me and not getting on with my life. I feel trapped, stuck, and useless in the face of all of it.
