So, I've worked with lots of different types of kids over 27 years as a high school teacher, Special Education Teacher, Childrens Counsellor and childrens author visiting schools.
Types of kids
Some kids are obnoxious, but suffering with poor confidence underneath. Some are highly anxious and get into conflict with everyone. Some are hyperactive and no one knows who they truly are. Some struggle to make and keep friendships going and yet are sweet little people. Some walk around in a daze, oblivious to what is going on around them. Some function well and seem happy. Some seem happy but suffer crippling depression and stress that they are incredibly good at hiding from others, including their parents.
See the world through their eyes
For an anxious child the world can be a scary place where they feel ill equipped to deal with what happens. The main thing to remember with any child is that their experience is unique to them. They sometimes feel they are the only person in the world who feels this way and that no one else understands. Accept that this is how they feel, no matter what your thoughts on it. It's important that you say, "So, what you're saying is.... Hm. That sounds difficult." And build from there.
That's why it is so important to LISTEN, even if you don't understand or don't know what to do with the information they give you. To get a snapshot into their world you must first open your eyes. Stop telling yourself that its just normal kids stuff and will blow over, because for this child, it might not. Don't take the risk that it develops into something far more serious than bedwetting or tummy ache before school. Get to the bottom of the problem. It may just be how your child sees the world that is causing confusion and thus anxiety. Are they a bit quirky? Do they have very specific talents and a narrow range of interests? Is their learning style visual, auditory, kinesthetic or multimodal? (see more on that here: Learning styles)
Anxiety is not a cause
Don't look at anxiety as THE PROBLEM. 99% of the time it's something else and anxiety is A SYMPTOM. At the base of all anxiety are thoughts, often very intrusive thoughts that replay over and over and become almost like an unwanted mantra. If your child is naturally anxious, that is, they catastrophise over what might happen and feel sure it will, there are lots of ways you can help! It is not a life sentence to always be at the mercy of your fears or worries.
