I tend to get a very unpleasant/tingly feeling in my belly (http://imgur.com/4H4OJqO to be specific) when I think about past or future events.

For instance, 3 weeks ago I went to a party with 2 (quite good looking) girls that I've never seen or heard of. The whole week before that party I had this feeling. I think its related to anxiety and low self esteem because I have thoughts that tell me I am ugly and that I will make a fool out of my self.

I ended up sleeping with one of the girls and I had a great night. Now, were going to a party in 2 with the same group of people. But as soon as I contacted these 2 good looking ladies this feeling went back instantaneously.

Its so distracting and annoying! I rather get kicked in my belly really hard and deal with the physical pain instead of this. Its driving me nuts!

Can anyone explain?, I'm 19 years old btw.

This is also the same spot where I feel the sense of emptiness. Most people feel that in their chest but I feel it right there.
