I'm seeing a therapist to improve my mental health.  I don't think I have any really specific problems, but it helps to talk to someone.
World Health Organization says that mental health is subjective and perceived by self-efficacy and a few other things. Do you think just talking to a friend would help?
Possibly!  Talking to anyone is pretty therapeutic.  I think that just letting your feelings be known to others really lifts a burden from your mind.
I totally agree. Plus therapist take your money and never really give you advice.  They have a way of getting you to answer your own questions. Do you think you are depressed or anxious? Those are very common issues in mental health.
I may have had some bouts with depression, but I don't think it was ever really serious.  I'm married and my wife helps me with a lot of my issues.  Some therapists are really good though, and offer valuable services to people that really need help.
I agree some can be helpful if the patient is willing to do the work and accept help. I myself have anxiety but I found my own ways to cope. Talking to one close friend really helps with my own mental health!
I think that's really the key - voicing your problems to a sympathetic person.  That can make a huge difference in your stress management.
Another key is positive psychology.  This is a focus on being happy and enjoying a meaningful life; whatever that means to the patient.
