You're quite right that this is Fi in distress coz it's trying to figure out who she is and she's using Te to let off steam. But that doesn't make her ESTJ. Unless you wanna call me ESTJ too.
And you may not appreciate the way she goes about it, but it's a forum, so ignore the threads if you don't enjoy it. She's appologized and explained herself enough, imo. LL, here's a tip for ya, try ranting to someone you know won't take it badly. Doing so in public always gets you bitten in the ass, ime. But do rant. You need it
Just don't get stuck in a loop. Rant, and self-reflect. It'll get you the answers you seek.
