Only a qualified mental health professional can properly assess and diagnose a mental health condition, including Dissociative Identity Disorder (DID).
If you are experiencing symptoms that concern you, such as dissociation or memory issues, it's essential to seek help from a licensed mental health professional. They can conduct a comprehensive evaluation, discuss your experiences, and provide an accurate diagnosis based on their expertise.
Remember that there are various reasons why individuals may experience dissociative symptoms or memory difficulties. Trauma is a common factor associated with DID, but it's not the only possible cause. Other dissociative disorders or mental health conditions might also present with similar symptoms.
Additionally, hitting one's head against the wall to go back home, as you mentioned, is concerning and should be addressed with a healthcare professional promptly. Engaging with a mental health professional will allow you to explore your experiences, emotions, and behaviors in a safe and supportive environment.
If you need immediate assistance or feel overwhelmed, consider reaching out to a crisis helpline or contacting a mental health emergency service in your country. They can provide guidance and support until you can connect with a mental health professional.
