Why do I behave so awkwardly in social situations? Was this awkward?

I'm more annoyed and frankly pissed off with my mate. I just texted him 'THE NEXT TIME YOU TELL NOT TO BE SHY IN A PUBLIC PLACE OR A SOCIAL GATHERING, YOU WON'T HAVE THE TEETH TO SAY IT ANOTHER TIME. WATCH OUT AND DON'T ****ING DO IT COS IT ****ING ANNOYS ME'.

You should've said this on your mate's face at the gathering.

Nice! He got told.

Yeah but now I'm sitting and wondering, that if I could be so forthright with my friend, why didn't I go and tell that girl that? Like when she asked why I wasn't eating, I should have said, 'I don't want to ' or something like that.

It doesn't matter anyway, and she was only asking you repeatedly because she was trying to be a good host. Seriously you should stop dwelling on it now as I doubt anyone else really cares. Enjoy yourself!

I know I should stop dwelling on it. I just feel bad though that I can't be like everyone else.

dude, whats the harm is grabbing some food and pretending that you're the most voracious kind of human being possible.

With the girl when she said ur hand is empty u should have said, ur hands are empty do u want my c*** in them

I feel your pain!! I don't get why people have to keep pestering you if you're shy ffs it just makes it worse, but I'd have done the same as you so I'd say you didn't make it awkward..

I tend to be quite shy in big social situations and always tell myself that I'm going to open up and talk more, but IT NEVER WORKS! I used to think of what I was going to say but have stopped doing that now, I tend to go with the flow. However, after every social situation, I just feel like an idiot and hate myself. Here's what happened today; I felt extremely awkward.
So I went over to a friend's place for a screening of a short handmade film he's made. There were a lot of his friends there, around 15 of them who I didn't know but did know one guy really well who I was with most of the time.(Anything wrong with that?). So after the film, there was some food and drink and after I finished eating, this girl comes up to me and says 'Why are your hands empty? There's so much food going around. Have something!'. I mumbled that I was full, but my idiotic mate made it worse and said, 'Oh come on, don't be shy, have something'.
Then later on, I was eating something and the same girl says 'Oh good, you've got something in your hand now!'. And I just smile awkwardly, SHOULD I HAVE SAID SOMETHING? And then the third incident, sorry for rambling on, but this guy came in with something on a tray and offered it to everyone. I refused, but this girl(not the same one as earlier) said to me, 'Hey didn't you want one of these'? I , again mumbled, 'No no, I'm fine' and again my mate went on 'Have some, don't be shy'. GRRR.. **** ..I just feel so odd and out of place sometimes.
Would anyone here have reacted differently? And now I'm thinking all sorts of situations, whether I should have said anything different or behaved differently or whether my friends would have reacted the same way in similar situations..

Oh you're cool

Win.
