I saw 3 people who my parents took me to when I was underage. Two of them were straight up terrible, one guy was quite ok but not for me and at that moment I didn't want to do therapy so it didn't work out anyway. Each of them I saw only once. Anyway that was kind of forced on me so I don't really count that
Then, as an adult, when I was trying to find a therapist for myself - I first saw someone who was basically shit and the kind of "just imply you are suicidal and I will send you straight to the ward". One session and I never came back.
The second person, this time I actually did better research to pick someone who seemed to fit my needs. And I found someone who was, well, not annoying as fuck, also not great, just decent. I felt like these sessions didn't help me at all, but I decided to give it time and went there like 3 or 4 times.. then I was like, fuck all of this, I told that therapist I won't be coming anymore because I planned to CTB that night
Around a year later I tried for the third time (kind of forced again, but that's a different story) - another person who I wasn't really convinced to, saw her for like 3 or 4 times and decided she's simply not a good match for me. I felt like she did not understand a word from what I said, just kept repeating some pre-programmed phrases and kept suggesting things that were completely irrelevant to my life.
And then directly after that. I was kind of ashamed to do it but I messaged my previous therapist (the one who was "decent") and decided to try again with her, maybe giving it a bit more time. Now I think it's the correct person, I've been seeing her for around a year and it has helped a bit, nothing revolutionary but worth it I guess.
I was very lucky that I found someone decent so quickly. Also I can talk to her about being suicidal because she has the approach of "well it's your own life and your own choice", I don't feel like she's forcing mento stay alive, just helping to find some things that might make me actually WANT to live.
