i have a friend that i just saw today in person (we both got vaccinated and restrictions lessened so we were able to hang out in over a year). they were wearing shorts (it was really hot out) and i saw some cuts that looked recent. i didn't bring it up because i noticed they kept pulling their pants down to cover them. i don't know what to do now. i want to let them know i'm here for them but i'm worried because they clearly didn't want me to see them (but i think they knew i saw). i don't know if they are getting help for it either. do i say something and how should i go about it?
