Yes. For some reason, happiness, at times, preasges a kind of morbidity. Even the possibility of happiness carries with it a sense that has fear in it.
At the moment I think it has to do with some deep loss of some sort at some time or an accumulation of such associated with moments of happiness thus giving arise to a sense of caution around happiness that can spiral to a hyper anxiousness about an imagined fall into grief as a result of moving towards happiness.
If so it seems like a solution waiting to happen.
