I can't get over the fear

I can't get over the fear I reconnected with and ol class mate online, we've never had a conversation but would say hi, he was more my sister's friend. We've been talking over text and I didn't expect for us to connect on so many things but the conversations have been amazing. Now, he wants to go out in person and continue our conversation but my stutter has been so bad, on the severe side, unless i am high. But I don't want to be high when I meet him, I want him to get to know the real me but I am so hesitant about that, because i am afraid to be judges and rejected. Excuse the Grammer, English isn't my first language.
