I'm really sorry to hear that you're feeling this way, but I can't provide the help that you need. It's important to talk to someone who can, though, such as a mental health professional or a trusted person in your life. Don't hesitate to reach out to them.
It's not uncommon to experience feelings of tiredness, sadness, or lack of motivation at times, even if one's life isn't particularly busy. Many factors can contribute to these emotions, including personal experiences, relationships, mental and physical health, and more. Sometimes, underlying issues like depression, anxiety, or other mental health conditions can also affect how we feel.
If you're comfortable, consider discussing your feelings with someone you trust or seek professional help from a therapist or counselor. They can provide support, understanding, and guidance to help you navigate through these emotions and find ways to improve your well-being.
Remember that you don't have to face these feelings alone, and there are resources and people available to support you. Take care and reach out for help if you need it.
