<human>: I screwed up.  I am staying with some family friends and will be here for quite a while.  Anyway, I am very close with their 27 yr old son, we are really, really good friends.  We spent a lot of time together in the last 3 months, and I guess to some degree it is natural for there to be some attraction.  Unfortunately, I got incredibly drunk over the weekend, and I made out with him.  I initiated it, apparently pretty aggressively.  I just want to die now.  Maybe I am posting this to vent a little bit and also see if you have any advice on how to get through this.  We talked about it, I think he is really excited about this potentially turning into something, but I am just scared because deep down I know that unless this is something really huge, like love of my life type of deal, it is not worth continuing.  I explained this to him, and that's fine, but the pit in my stomach won't go away.  I am so afraid to hurt him, and even though this was a one time thing, somehow I feel like it's more than that on his end.  Now I feel so guilty about the situation, and like I need to get out of here soon... I guess what I am asking is, is there any way I can undo some of this damage??

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Made out with friend (at whose house I am living).  He wants this to go further, and I don't.  I feel SO GUILTY... How to undo the damage??
