Reading the little you have shared, it sounds like your parents are fairly controlling - they control your schooling, your diet, etc. I’m not being critical, just making an observation, but I think that might lend itself to a good essay. Did you ever rebel against that? Are you looking forward to eating ice cream in college or do you think you will continue to follow the disciplined life style that they raised you with? Do you have a sibling and, if so, has he/she responded the same way to your parents’ influence? Do they parent the same way that they were parented or have they chosen a very different path for you than how they were raised? How does someone who is homeschooled develop interests in linguistics and CGI? Do you engage a lot with online communities and forums because of these interests and the fact that you are not in a traditional school? These are just questions that I had and would be interested in learning more about so one of them might make good jumping off points for an essay.
