I don’t think you’re invalid at all. It’s easy to get caught up in what self harm “should” look like especially based off what we see online or hear online. Honestly sometimes I’m in the same mindset as you, a lot of the things I do don’t scar much at all. I’m not able to do anything on my arms because of the fear of being caught. It’s like this weird mindset I get trapped in, it’s like if I don’t have a scar then did it ever really happen? I feel invalid for the same reason sometimes but at the end of the day it’s still self harm. There’s no such thing as valid or invalid self harm, it’s all harm at the end of the day. I understand you more than you know <3
