l did SI as a teenager for a short time, then it returned again when l was 44. People do all sorts of things to change how they feel, alcohol, food, sex, exercise, drugs, SI is just another method of changing how we feel. It is harder coping as an older adult, all the government funded help appears to be aimed at younger people. Weird? You and me both then, plus many more on here.
Keep safe. Soup.
