Keep working on your inner game , u are right things like that shouldnt rly tank it. Prepare to crash and burn, even with your friends gone it is still gonna happen over and over and over. The good part about it is that it grows a stonger confidence. ( U are here , reflecting , learning from your mistakes , if u would go out tonight and had the exact same thing happen it wouldnt affect u as mutch )
The easyest solution to this is dont take your friends sarging, if u are uncomfortable doing it solo , find yourself a nice mentor / wingman.
The last and most important part is u got to be "quick on your feet". Again this is a skill learned by practising and failing. The general spirit should be to try to make the best out of it , no matter what has happned. Let the AFC roll over and die in situations like that , u are not allowed to do that anymore
