As with most things in life, the work you're willing to put into the counseling process will determine what you can expect to get out of it. Counseling is a deeply personal journey and different for everyone.
No therapist has a magic wand or quick fix; you are the expert on you. Therapy works when clients find the courage to be extremely honest and vulnerable, open to understanding it's okay to be uncomfortable. Let's be honest...it probably won't be easy, but it will be worthwhile.
