I encourage you to speak with a therapist immediately. Do you have insurance to help you pay for a therapy session? Obviously, you must know that your relationship with your mother is not normal. You can not live your entire life based on her threats to commit suicide.
So, you need a next step. The truth will probably find its way to your mom, and you need some professional help to decide how you will handle a conversation with your parent who is not functioning within normal parameters. Are you ready to admit your failure, call your mom’s bluff, and move on to whatever it is you feel is the best course of action for you?
Do you have any relatives, friends, church or school adults that you can trust to guide you? Do you have another place to stay if your mom kicks you out? Use your time to think of what your alternatives are, instead of just focusing on keeping your mom in the dark.
In a normal world, it would not be a child’s job to keep their parent from committing suicide. You are bearing a larger burden than you should have to deal with. Please ask for help from others. This is not normal, you are not responsible for your mom’s unhealthy thoughts and actions. She needs more help than you can give.
The alternative for you is to live your entire life dictated by a person who is mentally unbalanced. Once this crisis unravels, she will create more chaos. It won’t stop unless you choose to act independently of her. I know that breaking away from this dominating figure in your life won’t be easy. That’s why you need to find help from outside your family. Professional counselors are trained to help young people who are caught up in these kind of situations.
Take a moment to assess your situation. Do you have any money saved up? Do you have a safe place to live, or can you travel to another place where you could live with your father or another relative or friend? Do you have a job, or can you get a job to get money to live?
School may take more effort than you are able to give right now. You don’t know what it will take to resolve the situation of failing out at your last school. You may not be eligible to attend another school if you still owe money. Don’t race into another academic situation without resolving the underlying issues. If your mom is your source of income to pay for college, you can’t depend on her right now.
Your priority is your physical and emotional safety. Your mom is going to explode when she finds out the truth, which at this point she probably highly suspects the truth anyway. Get yourself as far away from her as you safely can. She might try to harm you as well as herself if she gets into a rage. Do you have any younger siblings that live with her? You need to try to alert someone that can protect them also.
Even if your mom is not going to go through with her threat of suicide, her manipulation of you is still not a healthy way to live. You need to find different options that will get you away from her immediately.
