I reiterate above.

We are not in a position to make a diagnosis.

Similarly I discourage you from trying to diagnose yourself. The internet is good for researching but should never be used for self diagnosis.

I have several suggestions of actions I encourage you to make:

1. Seek out your school guidance counsellor. They can support you, provide some resources, and even get things started with seeing a doctor. If communicating with your parents is an issue the guidance counsellor can help you with that too.

2. Make an appointment with a family doctor. You are old enough to do so without parental permission. You are also old enough that a doctor must keep confidential your records if you wish them to do so. A family doctor will get the ball rolling. They can assess whether a larger problem is at hand and take action accordingly. This usually means referring you to a psychiatrist.

I see you are from NZ which I am very sure has a public healthcare system much lije -or even better I hear - than Canada. So, don't worry about trying to wade through the waters of payment, etc. Seeing a psychiatrist is free. When it comes to therapy there are psychologists available in the public system too. Don't let worry about financies prevent you from getting some help.

Are you able to discuss these matters with a parent?

3. Your local branch of the Mental Health Association will also be a great resource of information too.
