It means you aren't suited to run a public facing business. There's nothing wrong with that, but speaking as someone with a lot of social anxiety baggage there are things I'm equipped to do well and things that I'm not. I shouldn't let that stop me from opening a business if I really want to, but if I simply don't want to deal with the social rejection elements I have to accept that I'm better off letting someone else run that side of a business.
As for the non-business elements of your question, all you can really do is conduct yourself in a way that you don't believe you'll find yourself regretting later. If you say something in a public place, especially online, consider it part of the public record. It can and will come back to bite you later. Assume your [morally positive family member here] is always watching.
