Teen Idle is right - if it deals harm to one's self, then it's self-harm, by the very words and basic meaning that make the term. It sounds like you are substituting one form of SH for another. I know this might seem like a crushing thing to realise, especially if you've held high the month free of THAT word, but know that, as far as I'm concerned, it's still an accomplishment, no matter what anyone says, and well done for it.

A bit of my theory:

I'm fairly sure, at least in my case, that you truly know, yourself, if it's the bad kind of "self-harm", that is, not just physically damaging, but mentally/emotionally damaging. As I've said on other thread(s), we do things to ourselves that are harmful (yes, self-harm) like tattoos, piercings, and various other things, but it's not just about the actual harm, as it is the why of doing it - if the why is bad enough, then it can be so damaging to one's mentality, that it can worsen, and further warp the mind, hence what I often refer to as "fog"; the veil with which self-harm and depression itself covers self-harmers, allowing them to find illogical and irrational reasons to justify and defend acts of self-harm.
