Finding the right therapist to walk on this journey with you is the most important aspect of counselling, next to taking the first step which is reaching out.

Being ready to begin therapy is a powerful and courageous step, even if you’re unsure, nervous, or hesitant. Readiness doesn’t mean having everything figured out. It means you’re open to exploring your thoughts, feelings, and patterns, and willing to work toward some kind of change or understanding.

Here are a few signs you may be ready to start therapy:

Painted sunflower

You’re curious about yourself.

Even if you’re not in a crisis, therapy can help you understand yourself more deeply, your habits, beliefs, and emotional responses.

You want to talk about things you can’t say elsewhere.

If you feel like you don’t have a safe or neutral space to open up, therapy can offer that.

You’re feeling
stuck.

You might not know what’s wrong, but something feels off. That’s a valid reason to begin therapy.

You’re overwhelmed, anxious, emotionally exhausted.

Therapy isn’t just for people in crisis, but these feelings can be important signals.

You’re ready to commit time & energy to growth.

Therapy takes honesty, reflection, and consistency, and being open to the process.

If you’re unsure, consider asking yourself:

What do I hope to get out of therapy?
What’s holding me back from starting?
Am I willing to be honest, even if it’s uncomfortable?

Therapist office in Port Perry Ontario

Port Perry Office

This session is meant to be a time for your therapist to get to know you and make sure that you can feel comfortable working with them.

Your therapist will go over your rights and privacy, such as confidentiality, and you are encouraged to ask any questions that you might have.

This first session is also a time for you to assess the therapist to ensure that they are the best fit for you. This first session begins the rapport building and not everyone works well together.

The approach that Island Waters is a holistic one, which means in this first session, your therapist will ask you questions about various aspects of your life to get a better sense of your overall well being.

A treatment plan is then developed together to meet your needs in the most effective way. This will include goals, or areas you wish to focus on in your future sessions, and the frequency of appointments. If you feel that the therapist is not a good match for you, referrals can be provided to you.
Please know that questions are encouraged, and there are no wrong or bad questions.

Our Evidence-Based Approaches

View All FAQs
  • CBT stands for Cognitive Behavioural Therapy and it helps us to recognize and change thinking and acting patterns that have been unhelpful.

    The basic idea is that our thoughts, feelings, and behaviors are interconnected and by changing negative thoughts and actions, we can improve how we feel.

  • DBT stands for Dialectical Behaviour Therapy, and it helps us to understand our emotions and how to manage those emotions so we can be more focused and present in our everyday lives.

    This approach helps us to pay attention to what matters to us and “bounce back” more quickly when facing tough challenges.

  • Mindfulness therapy is about paying purposeful, nonjudgmental attention to the present moment to manage difficult emotions, thoughts, and behaviours.

    It’s about changing your relationship to your thoughts, and learning to notice your experiences with awareness and compassion, rather than reacting automatically.

  • Narrative therapy views us as separate from our problems and focuses on the stories we tell about ourselves and our lives.

    The main idea is that our “life stories” shape our identities and by reviewing and rewriting these stories, we can find new meaning, strength, and possibility.
