I've mentioned to T how other people have "really hard lives" etc. and "real pain" and feel quite similar to you. While I do have some past trauma, its no where near (imo) what I see other people go through. And I didn't start self harming until I was in college - so I do also feel like my "right to do it" can't be validated (told T I felt like a "fake" self harmer...) But T told me, and now i'm telling you - that pain is pain. No matter whether it is being experienced from a blade on a wrist or a pinch on the arm. The person is still feeling pain. Don't minimize your struggle or allow yourself to invalidate your feelings. It's okay to feel down, it's okay to feel bad. Sometimes people get sad in the middle of a joyous occasion - it's just part of how our emotions work! It's not okay to hurt yourself (you're worth so much more!) - but it is okay if you do it and you deserve just as much support as the next person.
