If you're struggling with substance abuse, it's crucial to seek professional help immediately. You can reach out to a therapist, counselor, or addiction specialist who can work with you to create a plan for managing your mental health and substance use.
Remember, there are resources available to help you through difficult times. Don't hesitate to reach out to a mental health professional or a helpline in your country. In many places, there are hotlines and support organizations specifically dedicated to helping people dealing with mental health issues and substance abuse.
You are not alone, and there are people who care and want to help you get through this. Please take the first step and talk to someone about what you're going through.
