RYL Forums - Um how to put this

I've been through the mill these past 2 days...And really didn't think I'd do anything about it; I signed up on here in the hope that there might be someone the same as me and it's worked, reading people's storys my problems seem minor. But I might of lost a best friend and the worst I've done about it is get drunk. Earlier today I was scrubbing some pen off my arm and I didn't stop, I didn't stop when my skin got red and I didn't stop when a white patch appeared of my arm. I stopped when I could feel my skin burning and now it's all weepy and sore. I just wanted to know if the weeping should be a concern to me or shall I just leave it. Another thing, do I cover it or do I let the air to it, my mum says leave the air to it but I'm not sure. Replys would be helpful =]
