I do, but probably not to the extent that you do. It usually only happens to me when I'm overwhelmed and have many things going on. Sometimes I'll take the time to try and unravel the emotions and figure out why I'm experiencing and why, other times I just don't give a s*$t, and try and focus on just being numb to the point I don't feel anything at all. I'm not sure if tht is a healthy thing or not. For me, I'd rather feel nothing, than feel sad.
The emotion regulation section of dbt does a lot of good for helping understand emotions.. such as prompting events, after affects, and other emotions that can follow.... you can read all about that here if you like...
