Don't understand why I did this
I have a history of self harm fantasies but not action. Today I went on a long walk specifically with the intention of finding a private place to hurt myself and went through with it. I wasn't thinking and did it right on my hand where it's extremely visible. It will almost certainly leave a scar, and a pretty distinctly self-inflicted one.
The thing is I was feeling fine today. I was not having any of the emotions or ruminating thoughts I associate with the desire to self harm. During my walk I was actually listening to a podcast that made me really happy and having a nice conversation with a friend. And then just casually burned myself on purpose because I wanted it to hurt.
I've been googling the method I used since getting home and it's sinking in what I actually did. That I'm going to be healing this for weeks and there's a high risk of it getting infected. That if anyone sees it there are very few if any reasonable excuses I can give for where I got it. I'm supposed to be going to bed right now but I kind of feel like throwing up. I don't know what happened and I want to talk about it but I'm just really ashamed of myself and I don't think I have anyone I can admit this to who won't make me feel worse.
I just don't understand. I feel like I can't trust myself.
