You mentioned that you have “ticks.” “Ticks” can have a variety of meanings depending on how an individual utilizes the word. Your defined meaning of the word is not fully clear to me. I am not certain if your “ticks” refer to a thought, an emotion, or a behavior that makes you angry or upset.
In the mental health arena, “tics” are repetitive, involuntary movements and vocalizations that are associated with Tourette syndrome. Tourette syndrome is a nervous system disorder that often begins in childhood.
Because of the limited information provided, I cannot answer your question: Do I have a mental health disorder or am I “just being a teen? Generally speaking, if you have difficulty controlling your behavior, you’re having problems in school and you have lost your ability to concentrate, then professional intervention is suggested. Those symptoms may be indicative of a possible mental health disorder.
My recommendation would be to have both a medical and psychological evaluation. If your parents are unwilling to have you evaluated, then speak to the school guidance counselor about your symptoms. He or she could help to clarify whether intervention is needed. In addition, the guidance counselor could speak to your parents about what course of action would be appropriate in this situation.
If you would like to write back and provide a more detailed explanation of your symptoms, I may be able to better address your question. Please take care.
