I'm going on a date tomorrow and I haven't been this nervous in a long time
Why are you nervous about a date?
She is a perfectly nice girl but I'm afraid she won't find me attractive.
It's normal to be nervous before a first date, but don't let it overtake your emotions or else she will notice. Try to play it cool and realize that she's probably just as nervous as you are.
I'm a terrible emotional person, this is why I don't have many friends.
Just try to calm yourself down. Nerves are a normal part of this process, just don't get yourself too worked up. You will be fine!
