Congratulations on a week of being harm-free! That's really a nice step forward.
You should want to do it for yourself, not because people will think you are weird cutting on your legs.
Set some more goals, go another week, and then another. wear shorts.
When you are able, try to throw away your blades, or hide them away where you aren't gonna see them right away, or a drawer you access daily.
Good luck, and keep your head up!
