Why do I get paranoid

Why do I get paranoid about what IM’s mean? It’s hard not to read into the black and white (or coloured, if you’re really origional) thoughts. Just now someone said a hasty goodnight and I could have sworn I felt dissed/rejected/curious/anxious just because it took less than a minute and I didn’t get a chance to even say goodnight. Man am I a mental case. I’ll stop being one if I can. People do what they want and what should I have to say about it? Goodness… It’s just that this individual’s opinion of me matters a whole lot and it seems as if I’m not helping that… or something i say just makes them mad or… bored of me or…something. See? Reading into things. That’s not supposed to be my job description! Ugh, I frustrate myself.
