It helped me a little bit when I was in my 20's because of my agoraphobia, but I lost a lot of money and it was quite intensive sessions for years. And now I'm 43 and my life is ruined because other trauma happened and I'm disabled.
So my opinion about psychotherapy is :
PROS :
- if you have enough money, why not (for young people, try to ask your parents to pay it) or maybe in your school you have free therapy
- it's always good to talk face to face with a good therapist
- you can discover things from your past and work on it (you realize things from another angle)
CONS :
- it costs a lot of money if you need a long term therapy
- you don't have a guarantee it will work
- you'll need to talk about your traumas and you'll cry sometimes
If I had an advice : try 1 or 2 sessions with the same therapist, and if you're not comfortable with him / her, change for another. Good luck !
