@rick well, talking to her instead of just staring and pretending nothing bad happens would be a good start.
If i were to have a kid with such problems i would try to help in any meaninful way, of course not by forcing random friends into her life, but mostly trying to put her in situations where it's easier for her to make friends, maybe putting her into some kind of club or fun extra-curricular activities would help... see what interests her and try to make her get together with people that may share her interests, idk.
Sometimes random events like bumping into random strangers help, but not always and they are rare events, and the pasivity of the parents really troubles me.
@Reluctant_Weeb @rick i think good part of the difficulty that people like that (like me) has to initiate relationships is the lack of self esteem, and the lack of self esteem stems from the lack of perceived accomplishments. Despite her being good at the guitar, she has problems with that because i think she didn't had a proper route or path of milestones to gauge her progress.
