F D,
Oh honey, I am so sorry. I remember your first post about whether or not to medicate. That was only a little while ago. Did you decide to medicate? Has the medication had a chance to work? I only ask that question because I remember when my brother was a teenager they put him on anti-depressants (suicidal), and after a couple of days he got really upset because he didn't feel any better, but the meds took a couple of weeks to build up in his system before they would change how he felt, and he didn't understand that. If I were you, when I spoke to the doc, I would find out if the medications you have started recently, if any, would be effective yet.
My heart goes out to you and to your other child. Does he see a counselor of any kind? If not, you might want to consider that for him. Living with a sibling on the spectrum is a big deal, and any child witnessing a parent being hurt could use it. I'm sure he's afraid for you, frustrated with living with the meltdowns, angry at his brother for hurting you, even when he knows his brother can't control it, all kind of emotional baggage, and I bet for him it really does sound like making his brother go away is the best solution.
And sometimes it is. It's hard, when you've taken care of a child every day of their life to have to sit back and examine the possibility that the job has gotten too big for us. And the small, secret part of your mind that says, Yes, I'm tired, and I just want it to be quiet here makes us feel guilty, selfish, and ashamed. So we push away the option, and keep going on, because we feel bad even thinking about it. BUT, your other child has feelings, too. And he's afraid in his own home.
A residential facility where your son can work with therapists and doctors intensively to leanr how to control frustration and anger, to improve his expression of emotion, could change his life forever. It could give him the tools he needs to function in larger society, to someday have relationships with people outside of the family, to live a richer and fuller life. You may be able to bring more services to him in that environment than you can at home. I don't know much about NM, so I don't know if you have access to a behavioral consultant, and a TSS, and a mobile therapist and all of the wonderful professionals who can really help a child on the spectrum. If you have a great team in place and your son is making solid progress toward his goals, then maybe this isn't the thing for him.
But if he doesn't have services in place, and the school district or your county offices aren't helpful, then considering all of the other options to get him the help he needs is part of being responsible as a parent.
I'm not saying you NEED to do this, or that you're a terrible parent if you DO decide to do it. Only you, your husband, and your son's doctors can make this decision. But I want you to know that there are people out here who understand how agonizing this choice is, how heartbreakinig it is to even consider it, and who won't judge, no matter which road you take.
