Self-defeating patterns come in many forms: Overthinking/rumination, racing thoughts, avoidance, lack of motivation, engaging with intrusive thoughts, anxiety, depression and more.
To address these patterns I use an evidence-based approach that combines traditional cognitive behavioral techniques with Buddhist-inspired mindfulness practices. This will help you change your relationship to your inner world and give you more control over your actions, leading to more life satisfaction. Clients of mine report coming away from therapy with an ability to "make sense" of their internal experiences, allowing them greater control of their lives.
Therapy can be a huge step in committing to improving your life, and I would be honored to take these next steps with you. You are the expert in your experience, and my job is not to "fix" you, but rather to work with you to maximize your potential and live a life that is more fulfilling.
