Not getting blood on things
Not having to deal with wound care
Dogs always noticing and sniffing my wounds through clothes
Getting out of long sleeve/trousers jail
Walking/using my arms with less pain
Not having scares about infection, blood loss, nerve damage, scars affecting mobility, etc.
It's easier to manage my POTS and anaemia without sh
More free skin for tattoos
The exhaustion after harming
Less self harming means slower progession of the severity of my sh (no sh means no progression)
Finding things I enjoy instead of just harming
Not having to weigh the pros and cons of getting medical attention
Breaking the connections between certain things and self harm (ie specific music, places, items)
Helping other people who sh
Also, rewarding yourself for being sh free or self harming less often! Buy yourself a treat, start a paper chain or bracelet/necklace to add to when you're sh free for so long, get a piercing or tattoo, etc.
Dealing with used bandages, etc.
