I had a therapist through Pineapple Support a few years ago.
I think it only took me a couple days to about a week to hear back from them when I applied. It's strange it took months for you to hear back from them, but if I had to take a guess, it's because they have therapists who volunteer with them and the therapist they pair you with has to be licensed in the state/region where you live. Maybe they didn't have any available therapists where you live until recently? Just a guess.
Overall, I had a good experience. But, with any therapist, your mileage is going to vary, and you have to find someone that you can click with. With PS, since there's not a ton of therapists who volunteer with them, you do run the risk of being paired with someone you may not click with. Therapy is definitely not one size fits all. When I was still doing therapy, I didn't like conventional talk therapy. There's nothing wrong with it, but it's just not what is beneficial for me. The therapists that worked for me were therapists who gave me constructive criticism, gave me "homework" to practice on my own, and challenged me. The therapist I was paired with was a wonderful person and we got along great, however, it ended up becoming more like I was talking to a friend rather than a therapist, which isn't necessarily what I wanted or needed at the time. But, just because that didn't work for me doesn't mean that it wouldn't work for someone else. And I still did enjoy my therapy sessions.
Also, PS only pays for a certain amount of sessions. I think at the time I was seeing a therapist through them, it was ten sessions. My therapist through them did offer to reach out to PS to see if they would pay for more sessions, since they do sometimes do that if they are able to afford it. I just know at the time, apparently PS wasn't getting enough donations to pay for any more than ten sessions. It could be different now, though.
I think if you feel like you could benefit from therapy, it's absolutely worth a shot!
