I love my girlfriend, she is the nicest person in the world...
But she is very insecure... Everyone loves her (because she is so nice), but she won't believe this. She seems to analyse whatever people say, or if they don't respond to a text, or look at her the wrong way, and make out that they don't like her or that they are annoyed about something she did, or something or other.
This is starting to get annoying, because if I say something, she will take it up the wrong way, as an insult. Then when I try to explain myself, she will question the way I phrased it, and say something like, "well you wouldn't have said it that way if that's what you meant", and stuff.
It gets worse when she is stressed (e.g. studying for exams), and she has this habit of storing up bad thoughts in her mind, which interfere with her study, which increases the stress, which makes the whole thing worse. It sometimes makes her get pissed off about insignificant things too.
I really want to help, but I find it impossible to reassure her about anything, she tends not to believe any compliments (although partly my fault as I'm not very good at complimenting)... I am not entirely sure she trusts me (though she assures me that she does) and whenever she complains about her problems, although I'm perfectly willing to listen to them, she stops herself and says, "You don't want to hear all of this" and stuff.
