Fearless, just hang in there. This day will end and another day will start tomorrow. Venting is a very good way to ease the pain you are in.
Being the parent of a kiddo with Asperger's is really, really, hard. I have worked for many years with parents of special needs children and have seen firsthand how difficult that job can be. It is kind of like living on a roller coaster. You can be moving along at a good pace and then, wham!, a big curve ball throws you all off kilter and you are plunging down and are not sure what is going to happen next.
Make sure to find time to be good to yourself. Take care of yourself. You are important, you are needed, and you are doing your best. Sober.
You are in my thoughts.
