Do you think just having some fun, lighthearted conversation with the people you can reach out would help? You could just say something like "hey, I'm having a hard time, do you think we could just chat about whatever for a bit to get my mind off of things," or however you want to word it.

Or maybe just asking to vent about it, or have a place to openly talk about it and work through why you want to self harm and come up with solutions would help and you could ask to do that?
