I'm introverted as heck, but there's no way I'd put off eating to avoid someone.
I can understand it to a point, but honestly you should care less. the only thing I would find a bit awkward is the freedom of having the kitchen to yourself, but in a student house you need to be with friends. So yes about space, but no about what they might think.
The danger is it adds to your anxiety and blunts your social skills, then you start hiding in your room etc. Having your own kitchen is cool.
