I'm really sorry to hear that you're feeling upset about this situation.
It's important to understand that dissociation and dissociative identity disorder (DID) can be complex and challenging to diagnose accurately. At your age, the experiences you're going through may be confusing and difficult to understand fully. Your therapist's perspective is based on their clinical experience, and they are trying to provide the best support they can based on their understanding of dissociation and DID.
Regarding alters, some therapists may use different terms or models to describe these experiences. While the traditional DID model refers to "alters" as separate identities or personalities, some clinicians might refer to them as "parts" or "aspects" of oneself.
It's crucial to remember that regardless of the terminology, what you're experiencing is real and valid. Your feelings, thoughts, and experiences matter, and you deserve to be heard and supported.
If you feel that your therapist is not understanding your experiences or if you have concerns about your treatment, it's essential to communicate openly with them. Let them know how you feel and what you're experiencing so that they can better understand and support you.
If you still feel uncomfortable or misunderstood, consider discussing your concerns with a trusted adult, such as a parent or guardian, who may be able to help you find a different therapist or seek a second opinion.
Remember, seeking professional help is an important step in understanding and coping with your experiences. If you're feeling overwhelmed or distressed, don't hesitate to reach out for support from a mental health professional or a trusted adult in your life.
Lastly, please know that you are not alone, and there are people who care and want to help you. Reach out to those around you for support, and don't be afraid to ask for help when you need it.
