If you are feeling stuck that means you are stuck somewhere emotionally. Therapy will go to where you are stuck and work at helping you to be released.
If you are stuck at a stage in your life, that stage could be a trauma or a childhood experience.
The therapist will go there with you emotionally to help and support with insight to what is holding you prisoner in the location or place you are stuck at. The therapist will work through this place of being stuck so you will be free to go forward. And be free to live and enjoy their life.
