Please don't give up eating gluten until you've had a Coeliac blood test done by a fully qualified doctor. Simple to do now - but many people here will tell you how horrible it will be to do in the future, once you've been on a gluten free diet for a while (because gluten has to be reintroduced for the test to work).
Why do I mention it? Because I thought I was lactose intolerant and a bit anaemic. I was - but they were caused by my being a Coeliac! Luckily a clued up doctor did my test as part of some other routine tests. Didn't I get a surprise...!
As for Vegan cheese, look out for Violife, Cheezly, Vegusto and Sheeze - amongst others. Some you may find palatable, others quite disgusting! For my money, Violife is about the best and is widely available. In my area Tesco's, Sainsburys and Asda all sell the original flavour. If you find a reputable independent health food store, often a variety of other flavours will be stocked. Even Holland and Barrett and Amazon sell it.
