I can understand and have had similar episodes in other situations. I am hyper-sensitive to negative things people say or do online or of being ignored. Last year (actually in 2012 when I first started at PC), my best friend on here started ignoring me. I started losing it and asked, begged another friend to call me just so I would know they were real. I told them I'd erase their number the instant we got off and I'd never call them back, and they said they would but never did. Between those two incidences, happening only minutes apart, I convinced myself that all of the people I'd met online didn't really exist and were figments of my imagination. I wrote a thread about it and a lot of people didn't seem to get what I was saying, kept saying that they were offended by my not thinking they were real and that they knew they were. It took me several days to gain a grip on reality. In addition, this continues to happen on occasion when I'm ignored or if a RL person I know only texts or emails me as communication.

I don't really know how you can move past it, but I believe I understand, albeit my situation was a bit different.
