INFP and INTJ I'd say. INFP works beautifully for me because they're just as muddled up as I am, but seem to have a serene approach to being so. A lot of times what freaks me out is my perceived inability to handle something. I'm not organized enough, I'm not disciplined enough, I'm not 'tough' enough, etc. INFP shares a lot of the parts about me I see as weaknesses, but handles them in a quiet and endearing way that makes me feel like I can be all those things without losing my shit.
INTJ is wonderful as well. They can get where I'm coming from with N, and help me analyze my situation, but that calm introverted energy, cool thinking function, and steady judging are like a pole to grab on to when I'm falling all over the place. I sometimes have to draw out the personally reassuring statements though. Sometimes I've been successfully talked down from a freakout, but just need that final 'you're not crazy' statement for closure.
