Hello and Welcome to Katherine Flechaus Counseling

Online Therapy for Adults in New York and Florida

Are you a high-functioning adult who feels trapped by anxious thoughts, self-doubt, or the weight of overthinking?


You’ve tried pushing through, but the same patterns keep repeating. Deep down, you know doing the same thing isn’t changing anything.

Do you find yourself:

  • Stuck in the same self-doubt patterns, struggling to set boundaries or find your voice

  • Battling low self-esteem while your inner critic gets louder

  • Feeling like an imposter, afraid you’ll be “found out”

  • Caught in endless cycles of overthinking, second-guessing every choice and decision

  • Drained by feeling you have to say yes to prove yourself and prove that you belong

  • Wondering if you are on the right career path

Therapy can help you:

  • Understand the origin story of your anxious, self-critical thoughts

  • Break free from negative loops and create new, empowering patterns

  • Feel more confident, competent, and connected in your relationships and daily life

  • Step into your goals with clarity and self-trust

For over 30 years, I have been working with adults who feel trapped in negative, anxious thought loops that keep them from living the life they have envisioned. Together, we’ll explore the root of what’s keeping you stuck and identify practical, sustainable steps to help you

move forward with clarity and confidence

Are you ready to:

Decrease Anxiety & Overthinking by breaking the cycle of negative thoughts and self-doubt caused by impostor syndrome,  indecision, or perfectionism?

- And begin to identify your strengths and meet your personal and career goals with confidence.

 Build Self-Esteem by replacing negative self-talk with self-compassion and confidence?

- And be able to connect with your worth and have the bandwidth to enjoy the life you have created.

 Improve Relationships by decreasing anxiety, being more present in the moment, and feeling less overwhelmed

- And have the emotional energy for your most important relationships and your social connections.

 Decrease Emotional Burnout by stopping the cycle of overcommitment, learning to set limits, and managing stress

-And start prioritizing your well-being and celebrating your successes.     

“Katherine is the absolute best. After years of struggling to find someone who could listen to me but also counsel, I am beyond grateful to have finally found her. Only great things to say.”
