The point of therapy

I’ve been in therapy for years, I’ve had so many different therapists, psychiatrists and forms of therapy’s at different organizations and literally nothing worked. Got diagnosed with chronic depression but that’s about it. I feel like I wasted years of my life more than I already feel like I have and I’m just wondering what’s the point of being in therapy if it doesn’t work?🫠 Do I just quit it and accept my fate or something?!
