yup... for me, it's because of those times when I have initiated and she doesn't respond I go into a tailspin wondering why. If I'm in a "dark" mood when that happens... oh man... it's like getting flushed down a toilet.
I think part of this is that my perception and understanding of the world (my friendships and all of it) is so dependent by what I'm feeling at that moment. So if I'm depressed, it's like, of course my friends all hate me and don't want to talk to me... I just don't know exactly why. If I'm feeling good, it's the opposite and there's no need to reasure myself of it. SEIs can be self centered creatures in some ways.
Also I'm probably not very emotionally mature (after 35 years I'm trying though
)
