I know what you're going through. Though I haven't been cutting for too long, I understand the fear of others seing my scars. Only my closest friends have. I hope eventually I'll be strong enough to wear a short sleeved shirt and shorts. I wear a bunch of bracelets on my wrists to cover the ones there, though the cuts and scars go up to my elbow.
I know how it feels but somehow I've been able to conquer it.
I used to be shy about my scars and would wear cover-ups in public pools and beaches. But then I've realized "who are they anyway?" I've learned to show my scars like battle medals and I've been able to build confidence as if my scars has nothing to do with how I look.
I remember when we first used our inground pool, I walked wearing 2-piece swimsuit and everybody was in awe, I don't know what they were thinking and I don't care.
