Hi, it seems like you are emotionally overwhelmed and finding it difficult to cope with the intensity of your emotions. At your age, you are also going through a lot of hormonal changes in your body which might be having an impact on your mood.
Next Steps
It will do you good to confide in a trusted adult ( parent, sibling, cousin etc) and share your feelings with them. Use your talent to creatively channelise your emotional energy.
Health Tips
If these symptoms become too overwhelming or start affecting your daily functioning, you can seek professional help. Speak to your school counselor or consult a psychologist online to discuss your issue in detail. Good luck!
