This is a common question, and impossible to answer for any therapist.
Why? Because every individual person that enters therapy is entirely different and it depends on the person.
Some factors that contribute and questions to consider are: How motivated are you to participate in therapy? Are you willing to commit to changes? Are you willing to come once a week? How long have you been suffering? What brought you in now? I know, that’s a lot, but those are topics we discover throughout the therapy process, together.
