I feel lonely and completely isolated. I don't know what to believe anymore. Recently, a former high-school classmate, who got into the same uni as me and never said hi to me the entire last year, suddenly initiated conversations. Fridays are not my lucky day, that's when it always happens. the fact is, her ignoring me last year made me reach a new low and get into harmful behaviours. I started theorising the reason behind her behaviour and I reached the conclusion that it's because of an embarrassing moment in my last year of high-school that keeps me up at night. I made a friend in uni and in a moment of weakness I told her about this former classmate and the reason I've been ignored. if the things got better with the classmate, they're now bad with the uni friend that suddenly can't stand me and is being meaner than usual. I can't be mean back: I'm afraid she would reveal the shameful incident. I fell into bad habits again. my other friends are too busy for me and I'm desperate.
