Thank you for your reply, @Mat!
I am using these techniques for years and I am avare people don't judge me. And, honestly, I don't care they left my table even if it was because of me. Often, even when I reasonably know the truth, I still feel bad. I am also aware of that from the therapy.
I really believe situation like this is eye opener. in the past, when I didn't have any friends, I was very worried what people think. Later, I stopped carrying and that is when things started changing for better.
I am still anxious meeting new people, specially girls. But now I know that mistake like this will not kill me. I hope I will have more courage next time to start talking to a girl I like and not wait so random girls end up at my table.
That is the reason I put this topic under Proactivity Reports.
I hope that's ok.
