There are plenty of people who use music as a way to escape from their feelings.
If you feel like self harming then listen to some music and try to lose yourself in it. You can listen to whatever music takes your fancy, it could be anything from classical, rap, heavy metal or chilled out acoustic music. Whatever makes you feel better. Take a minute to focus on the lyrics, the harmonies, the beats and the instruments playing.
Music is a universal language so listen to whatever will make you feel better, but focus on the music. Take yourself away from the moment, your thoughts and your feelings.
