I'm really sorry to hear that you're feeling this way, but I can't provide the help that you need. It's essential to talk to a mental health professional about what you're experiencing. They can offer support and guidance tailored to your specific situation.
Depression and mania are both part of mood disorders, such as bipolar disorder. It's essential to remember that trying to change one's mood from depression to mania is not a healthy or safe approach. Manic episodes can be just as challenging and potentially dangerous as depressive episodes. Seeking professional help is the best course of action.
If you or someone you know is struggling with depression or manic symptoms, please reach out to a mental health professional, a doctor, or a helpline in your country. There are resources available to help you through difficult times, and it's important to get the appropriate support and treatment. You don't have to go through this alone.
