I’ve been self harming pretty much all of my adult life, nothing to feel guilty about, it’s just a way of coping with your feelings. Although I do keep it a secret from nearly all people, an extremely small amount of people know I self harm, not because I’m an adult self harmer but just because I’m very private, don’t trust most people, and am very selective in who I tell. Most people don’t “get it”.
And in adulthood, the consequences are much harder to deal with.
