I'm 27 yo. i tend to do self destructives, how i avoid this? thankyou for your help?

You find a life coach/therapist who will teach you the skill needed to deal with stress in productive ways. They can also often help you uncover triggers to the behaviors that you were not aware of so you can focus on avoiding or mastering them.

You need help from a psychologist that can work on cognitive behavioral therapy and other techniques to help you gain control over your self destructive behavior. Start with your main doc who should be able to coordinate further as needed.
