My little dog died on New Year's Eve.
I came home, medicated and felt fine. I was on holidays, so I continued to medicate until one day, about a week later, I was cooking dinner. I burnt the onions and blew up, yelled and got all pissed off at my wife. Of course, it had nothing to do with the onions, or my wife, I just missed my little dog.
For me, it allowed me to push down and avoid some feelings, but eventually the feelings wouldn't be denied. They were still there, and came bursting out.
Somewhere you have to find a way to deal with your issues, because eventually, your onions will burn too, and whatever is in your noggin is going to come bubbling out.
Good luck.
