CMV: As a very introverted and isolated person I should still force myself to socialize regardless if it makes me unhappy

The original title I was going with was "Very introverted and isolated people should still force themselves to socialize regardless if it makes them unhappy", but I changed it to be about "me" instead. Hopefully my point goes regardless.

I am a person who does not crave socializing and spends most of my time alone. I don't feel happy, but socializing makes me explicitly feel uncomfortable and unhappy, the worst version being mind-numbing parties/drinking/concerts/sports and competitions. The only aspect of wanting friends is situations like having someone if I need to go to the hospital, borrow money, etc. Selfish stuff, not genuine respect.

The therapist's I have gone to only tell me "well, if you enjoy being alone and solitude there's nothing wrong with it unless you want to hurt others or harm yourself. Be yourself". I think this is wrong. I believe that I should not be proud of who I am and be comfortable with it. There's also a worry in my mind whenever I hear about shooters and such, because they are very often described as lonely and basically in my exact situation (without the women hating, racism, etc). So I could be looked down on for having these traits and probably should act otherwise.

I should continuously force myself to socialize for the rest of my life even if it makes me more unhappy.

EDIT: Lots of good comments, I'm going to go through them again and see if anyone is a worth a delta. But perhaps it would be unhealthy of me to accept that isolation, even if I give out a delta
