The behavior you describe is quite serious and not likely the result of puberty. The only way in which biology or puberty affects this situation is related to height. At 11 years old, you are “short” now but you will grow taller. Growth spurts among males typically occur between the ages of 10 and 15. Your height may not be fully determined until at least 16 or 17 years old, and maybe later.
I agree with your mother. It would be in your best interest to see a mental health professional. What’s most concerning is that you once lost control of yourself and attempted to strangle your best friend. It’s a definitive sign that you have the capacity to lose control and engage in violence. The concern is that such an event will happen again and you may seriously harm or kill another individual.
Tell your mother you wrote this letter and show her my response. Insist that she take you to see a mental health professional. Treatment can greatly assist you in learning how to cope with your emotions and to develop healthy behaviors. Please take care.
