Get a therapist who focuses in DBT. They can teach you skills to improve your emotional capability BUT never forget mindfulness takes both the emotional area mind & the logical area to function together to make wise choices for your life. Both areas of the mind are critical & there may be part of your logical mind (what you call MENTALLY) that isn't functioning with much needed skills either.

In other words you can't separate your logical mind & your emotional mind development. They work together. You have some concepts that don't go with the way the mind actually works. A good psychologist would be a worthwhile benefit to teach you the skills YOU NEED TO LEARN. It takes a lot of work & practice to learn skills that will help you..no magic wand works
