I don't believe that I have seen any statement that incels are freaks stronger than your own statement that "otherwise she might assume that I had gone to prison for 30 years". I'm sure that there are some people who might assume that -- or worse -- but I would not expect that most people would.

Likewise, when someone overshares about their problems (and if you defined yourself as an 'involuntary celebrate', you are framing it as a problem), the default social response is "don't give up, you can handle it!" whether you're talking about dandruff or cancer. Her response may not be what you hoped for, but it wasn't a clear indicator of prejudice.
