First dates advice

Hey girls,

So I'm going on a date with a guy whom I have been talking to for about 1 month now, we haven't met before even though we live around the corner from each other due to being busy. First of all I'm 16 and he's 18 turning 19 in September so is that bad, secondly I have heaps bad anxiety especially over meeting people in person so I'm currently freaking out and have already bailed twice, I need some dating advice please and some advice to calm my nerves. Thankyou!!

Update: lastnight was our second date, the first date was amazing I took advice and tried my hardest to not think anything of it, thankfully he was nervous too
