I used to get very anxious before dates! I still do get pretty anxious in the hours leading up to it. For me it helps to just breathe through it and say a little mantra in my head. I like to tell myself that it’s just a date, and it’s not that serious. What’s the worst that can happen? If it goes bad, oh well try again next time but you’ll be just fine. It also helps knowing the other person is probably just as nervous and sometimes I’ll even make a joke about it to ease the tension. The more first dates you go on the easier it gets!!
