It just seems too much...

So I asked for help, I shouldn't be surprised at what I got. Superman flies into town today to take over the decision about where our mother might be staying for the possible rest of her life. I asked for his help, his understanding of the situation here, and I got Superman acting like a dumbass.  While I understand most men are hardwired for a "fix," after 8 years of taking care of our mother EXCLUSIVELY, and 8 years of making decisions for her EXCLUSIVELY, I need a little respect.  While it was fine for me to make all the decisions alone, now he needs to be involved, telling me what paperwork he needs, telling me he needs to see the facility, he needs to talk to admin, he needs to come today. This is my last weekend before I start back to work on Tuesday. The summer as you could see from other posts has been fraught with mostly downs. The friends I would talk to that would say oh let's have lunch, a movie, never call back, and while I am not pursuing them, sometimes it is all I can do to get out of bed and carry on through the day at this point.  I needed them to carry through. He didn't ask if he could come today, he just said he was coming and he cannot take off during the week. Well frankly folks, this is a lie, he just went to see his wife's very weatlhy aunt for her 95 birthday in another state and more than likely took off a day for that. He had a new grandchild and he took off two weeks for that.  There is no courtesy, respect, consideration from my brother at all, again treating me like a 12 year old child, that while is responsible, only just enough to get things done, but not enough to respect my effort.
Not one thank you, sorry this is so hard, wished I could have done more, I feel for you and your daughter, appreciate all you have done for our mother, all the hours, money, angst, emotion you have put out in 8 years, just nothing.
I truly feel very alone at this point in my life, I have no one to help me, no one has my back, I can't call anyone and complain. Sure everyone says oh call me, but not really ... they really can't be bothered.
