I don't have that experience at all. When I'm upset, I'm really upset, and it pretty much stays until I do something about it. When I was a kid, I was upset a lot (just that kind of family) and I used to stuff the emotions away (that backfired, years later, when I had to finally deal with all of it). Even now, when something gets me upset, it stays present, unless I consciously dismiss it.
In fact, for me, dismissing pain and other strong emotions was very difficult for pretty much all of my life. It's only quite recently that I've been able to manage these emotions and let them go easily.
