I'm so sorry you are going through all of this. Having as child is hard work, I know. You poor thing. I was lucky enough not to have any of my 4 colicky, but I remember my nephew was and my sister in law used to put the vacuum cleaner on, or the dishwasher. It seemed the "white" noise helped. I'm not sure if it helped her not to hear him or it really helped him settle down.
I wish I could be of more help but I will keep you in my prayers.
just remember....this too will pass!!!!
