I want the answer to be no, but still I feel like I need to ask.

Background information
Last night I went through an anxiety attack, but with a few unexpected things happened. Say for example I felt like I was hurting myself because of all of the pain in my head. I felt like I wanted to wrip my flesh. I just couldn't stop. Lukely no see able damage, but I'm really sore.

Question
Is this concidered SI or just my alter trying to attack me?
