the therapist is not going to just say ok you're done goodbye the day you turn 18. Therapy doesnt work according to the clients age. But depending on the type of therapist you may be transferred to a therapist that works with adults instead of a therapist that works with children.

Who will you be when you turn 18 - the same biological you that you are right now. The only difference is going to be instead of using all those coping tools you have learned throughout your childhood therapy program you will use as an adult be it if you choose to get a job, go to college, get your own appartment, vehicle and so on that other adults do.

Basically all that is going to change on your 18th birthday is that you will legally and morally be considered an adult instead of a child.

There may be times when you need a therapist and there may not be but now that you will be an adult YOU will be making the therapy decisions of who you see and how often or if you rather not at all. As an adult all desicions are now up to you hey WOW you have a whole world that you can now explore and learn what you like and don't like, what you want to do and what you don't want to do. Just like any other adult in this world 18 years or older no one can force you into therapy or any thing else you want or don't want to do as long as you are not hurting yourself and other people, and are following the legal laws of your state, country. time to celebrate you are going to be an adult. It will take some time but as you explore you will know what your likes and dislikes are and what you want to do.
