There is no simple answer to this question. Sometimes people start to feel better quite quickly, and sometimes deep transformation happens suddenly. Often the simple act of telling your story and receiving support can begin to create change in how you feel.
It is also true, however, that real change can take time. It took your whole life to get you to where you are now, and it may take some time before you are able to feel things shifting. You may not feel better right away. In fact, sometimes people find that counselling stirs up a lot of stuff that was buried before. This does not necessarily feel bad, but can sometimes feel quite intense or uncomfortable.
In our first few sessions, we will talk about how long it might take to reach your goals for counselling. I will also check in with you regularly to see how you feel we are doing. Ultimately, it's up to you to decide how long you want to continue our work together.
