As someone who tried therapy and met friends who did it, it all depends on the problem and how severely it's affecting you.
Half the friends who tried therapy have had their lives improved, recovered from suicidial thoughts, and overall happier. The other half felt unheard, their needs unmet, and left worse.
For me, I was SA'd and possibly suicidial a result, and I had massive fear of adults. Instead of analyzing why I was afraid of adults, they called me non-compliant, a troublemaker, and treatment resistant. Diagnosed me with depression and medicated me, when realistically I should of been given PTSD or some trauma related thing. I'm glad I left and I will never go back.
I've lost friends because they couldn't accept I was traumatized by therapy. Therapy trauma is never spoken about in the mainstream media and leads people like me to feel more isolated and unable to speak up. And because it's promoted all the time, refusal to them sounds like "You refuse to change and will continue to be toxic".
I truly believe therapy can help some people, it saved some of my friend's lives, but I am sick and tired of it being an all around blanket solution. "Go to therapy" sounds like "I don't like what you're saying so fix yourself". Sometimes what people needs is reassurance, a change of diet, or even disposable income in this ever changing world. Not someone telling them to change their mindset and blame them when the world set them up to be in agony.
