Here are a couple good sites to help people find a therapist:

Filter by your needs(depression) and see who is near you. You can read their experiences and get a bit of a feeling of how they work. Once you short list a few, send messages requesting an intro call. Most will give you 15 minutes to chat and see if you both think it can work. Then you make an appointment with whoever you feel can most help. There is no magic here, but it's a good starting point.
There is pretty much zero help in the public system, so don't waste your time on it. You can find resources, but they are limited in the number of sessions and I found were of lower education and expertise levels. If you think you need more than 3 sessions, it's just going to be a waste of your time.
