Thank you everyone for your replies...

I guess it is helpful for many people when it is used to break patterns that are affecting their current life.

In my case, I believe the issue is that I can see how my childhood and adolescence contributed to messing me up, but I can't see a way out of it. I am an anxious, depressive and obsessive person. There is nothing really tangibly wrong in my life, except I cannot sleep well or stop obsessing about any problem I start analyzing. There is nothing I can really change in my life, it's the head I need to change.
