I've seen a few different therapists over the years, and yes, therapy helps me tremendously. People tend to have this stereotype of therapy as "blame everything on my mother" or "whine about my problems." I see a social worker who does cognitive behavioral therapy. My therapist is there simply to be an objective person who gives consistent feedback and constructive criticism.
For me, therapy is like problem solving that helps me deal with stress, anxiety, depression, etc. I've learned new things about myself and how I look at the world, and this in turn has empowered me to handle things better.
The best part of therapy, in my opinion, is that I can say what is really going through my head without "scaring" my therapist or stressing her out. It's hard to do that with friends.
