I'm trying to figure out what my best friend is, and I would say she was a seven, cause she is always in action, jack of all trades, has heaps of friends, isn't particularly sensitive, is generally upbeat, and is an ENTP...
But a few years ago she became a goth got really depressed, was cutting herself, and attempted suicide twice.
It wasn't reactionary depression, and probably not hormonal.
It probably spanned about 3 years, and if you met her now you'd have no idea (except maybe for the monroe)
What's kinda weird is depression is when you repress your emotions; it's internal. But she was very external about it.
Can this happen with 7s?
