Poor ability to express emotion seems more like what happens when Fe gets blocked, but maybe that qualifies under the "overindulgence/extreme neglect" rule.
I can get into a bad Ne-Fe combination sometimes and imagine all kinds of things about emotional states of others that is basically amplified noise.
I don't think I've ever had an emotional "outburst", but I have cried a lot after breakups, I guess that is closest.
When angry I get... tactical. I will destroy you. The angrier I get the more serious, quiet, and intent I get. I think this could be an E-9 thing, being pushed to the point of finally a) acknowledging anger and b) acting on it.
