Thank you for writing in for help. It sounds like you have an illness called major depression. While I can’t diagnose you in this forum, you do need to be seen and evaluated by a physician or mental health therapist ASAP. How brave of you to reach out to your mom for help, and I’m sorry she didn’t take you seriously. Did you tell your mom about the depth of your hopelessness, your self-harm, and how much you hate yourself? Please reach out to her again and be completely honest with her about the depth of your despair so she can feel the urgency. Sometimes parents don’t know how to handle a child’s emotional pain. Please go to her again and tell her in firm way, “Mom, I need to see a therapist as soon as possible. I am very depressed, I’m hurting myself, and having thoughts of wanting to die. I’m scared and I need your help. Please take me to the doctor or therapist.”
If your mom doesn’t understand depression or mental illnesses, you may want to have her read some of the resources on PsychCentral so she has a deeper understanding of what you’re going through. If your mom still doesn’t respond to you, please reach out to a school counselor or another trusted relative for help. There is help and treatment for the symptoms that you’re describing. Please continue to be persistent so you can get the help you need.
Take good care of yourself!
