i've been having a lot of thoughts

i'm not sure if this would be considered too graphic or not but i've been having a lot of self harm thoughts recently (in the past 2ish months. these thoughts consist of me brutalizing my wrist with a sharp object) and whenever i get these thoughts the area of my wrist just becomes really itchy and just slightly hurts.

i'm not sure why i'm getting these types of thoughts so suddenly and considering how i haven't even had the desire to self harm for maybe four-ish years?

i don't know. i don't really have anyone else to confonde these thoughts to or tell this to anyone who would really listen.
