Thank you for all the great suggestions, Gary, Artiste, Jeff, Kelda and Del! I'm going to try some of them, myself.
I also wanted to mention that, for people seeking therapy or services in other countries, I wasn't able to look extensively because English, unfortunately, is the only language I'm very fluent in. But I found the lists above simply by googling "depression" and "services" or "hotline," and it only took a couple of minutes to find those lists.
