A very warm welcome to the forums, I am also a Canadian living in Australia. I have been living here for about 14 years now so I am very glad that you like the environment and culture.
I am so sorry to hear that you have been going through this, I am so glad you have a support system in your church family however I can understand how isolating and stressful it must be to be in your position.
Can I ask, have you spoken to your GP and psychiatrist about what you are going through?
We are definitely here for you!
