Therapy hasn't helped me "break down any walls", but I have found it useful at times sharing my troubles with someone because it makes me feel less alone in it all.

I did therapy for 3 years, 1 year as a teen and 2 years in my early 20s. I had (diagnosed) depression for a decade+ for context.

I'll say it: it was completely useless, a total waste of time. I wouldn't consider speaking to a therapist about anything ever again.

There are a lot of useless therapies. I've been through several garden variety therapists and the cost was simply not worth it. Part of the problem with therapy is you know nothing about your new therapist, and more often than not the therapist has no idea what you're going through. So you lack the connection. The therapist/client relationship is very narrow and neutered and its easy to waste a lot of time.

However -- I did have some breakthroughs with a life coach I found watching youtube vids. It was really helpful for me to go into a therapeutic relationship when I already know I can connect with the coach on a personal level.

For me it was completely useless. I have tried to find evidence that it helps and have never been able to find any.
