There was this girl (almost 2 year ago) who I barely knew (we only had some wide-eyed-staring with or without smiling and some 2-sentence-soft-volume conversations during a few months). Anyway I was infatuated and I'm pretty sure it was mutual. At some point I moved away pretty abruptly she was quite upset. However after that day she never responded to any texts. I was extremely depressed in the first months and still very sad about it (I have a shrink). But why do I feel like this?
