Worst girlfriend of the year award goes to me!!!!!

So last night I woke up to go to the bathroom and came back to bed my honey also got up to go a few min after me when he came back I was already half asleep and he tried to cuddle with me but it startled me and I ended up hitting him in the nose which then began to bleed very dramatically I didnt mean to do it I was scared but when he got up to try and stop The bleeding I realized what I had done and my heart sank to the floor I cried and rushed over to help him. But I still can't get over what I did to him my heart has been heavy all day and every time I think of it I cry he assures me he's fine but I know it hurt him cuz he cried when it happened. I feel so bad I don't know how to get over this.
