There is a sticky thread at the top of the coping forum with some beginner info that might be helpful to you. Here's a link to it also:
Newbie Info 101
I can tell you that lots of adults have issues adjusting to the gluten-free diet. Changing your diet can be a little bit of a challenge. I didn't think it was real fun myself. But after doing it for a few years it became the normal diet to me and I didn't miss the other foods anymore. It just takes time and determination to make it work. A little pre-planning helps too. Like taking some gluten-free fruits and snacks with you on trips. Some of us pack our own lunches so we have something safe to eat. There are more restaraunts that make gluten-free food these days.
A good way to start eating gluten-free is to stick with whole foods and avoid processed foods. Eating mostly meats, veggies, fruit and nuts and not much in the way of baked foods. By doing this you avoid having to worry about the long ingredient lists on processed foods. Plus whole foods are better for everyone.
gluten-free is becoming a standard diet option these days. It's still considered unusual but is becoming more mainstream. One estimate I saw said that about 30% of the USA population has at least one of the genes for celiac disease. That's a lot of people that might get celiac disease at some point. Having the genes doesn't mean you will get celiac, just that it is possible.
Now for the scary stuff. There are a lot of potential problems that can develop in people with celiac who ignore the gluten-free diet. People tend to develop additional auto-immune diseases over time. This article has some info.
Celiac Disease Research: Associated Diseases and Disorders
In addition to the risk of developing additional diseases, there is the issue of just plain feeling crappy. Celiac disease damages the villi lining the small intestine. That damage interferes with proper absorption of nutrients, (vitamins, minerals proteins etc) that our bodies need to function and repair themselves and grow. Over time the body begins to fail due to starvation of vital nutrients, even though you are eating every day. People start feeling tired and foggy and sometimes grouchy and forgetful too. It's not a fun way to live. It's especially hard on growing young people's bodies as their bodies need lots of nutrients to build tissue and grow properly. Some kids end up being short adults or having other problems, like bad enamel on their teeth, hair falling out, skin rashes, etc. So celiac's nothing to play around with and treat lightly.
A tricky thing about celiac is you can't always judge the damage by symptoms. Some people have few digestive symptoms or even none at all. But their gut is still being damaged. That's called silent celiac. The immune response can be kicked off by a small crumb of gluten, and can last for months. So it can take quite a few months to get over a relatively small glutening. That's why it's important to avoid all gluten, even trace amounts.
Well, there's an awful lot to learn about celiac disease, but you don't have to learn it all at once. Once you decide to really go gluten-free, you find you start feeling better after a while. And if it's hard there are lots of people on this forum who can help with suggestions etc. We all went through the newbie stage ourselves so we understand how hard it can be.
I hope you stick around and do some reading on the forum. There are a lot of helpful people here.
