Yes, I do. I know that feeling very well. That's usually when I realize that something needs to be changed or discarded. Something fresh needs to be in its place. Missed opportunities and misplaced dreams need to be explored. Some part of me is being neglected and I have to find out what that is. It could be I'm imbalanced because I've been neglecting my body. But it could also be that I'm not using the right outlets for creative expression. You have to look for the source of pain. Pain is a signal that something needs to be addressed. You might keep ignoring whatever it is, if you didn't have that signal.
I force myself to feel it, there in that moment. Otherwise there is a tendency to push it to one side only to have it resurface at another time. If I can't create the emotions authenticaly I will listen to a sad song or watch a sad vid. I will set aside time to wallow, and then get up and get on with the day.
"Ruining the happy-go-lucky image", making this topic, strikes me as an attempt to forge a future weapon using credibility as it's metal for pms and chat. By saying it'll be ruined also reduces the potential losses by saying it yourself first, and through exaggeration you give others less room to escalate, which also makes it easier to contradict and resume things as they were before while still having this in your back pocket. I doubt you'll back pocket this, as you seem like one to work in the short term, so you'll likely be using this to prove something to someone almost immediately.
On topic, I try to force myself to think about it until it doesn't hurt as much anymore. It's better to have scars than scabs.
