Just because you don't break skin or use a razor doesn't mean it can't be self harm.
Just because they never hit you doesn't mean it can't be an abusive relationship/friendship.
Just because you can communicate in some circles doesn't mean you can't have anxiety or socializing issues.
Just because you have a good day doesn't mean you can't have depression.
Do not let your perception of how your struggle should be silence you. Your problems are real and they deserve attention. Please be safe.
