Son is nervous about starting high school. Any tips?

My son is 14 and starting high school next week. He will know a few people but there will be a lot of new people also.

I asked him if he was excited to be in high school and he said “not really.” I asked why he said “I guess I’m just kinda nervous.” I asked why and all he’d say was “I don’t know. It’s just a lot.” I’ve always thought he’s done fairly well on the social side of things.

He’s not prone to nervousness and he’s normally excited for new experiences but this time he seems stressed.

The only thing I’ve really said so far is just something along the lines of “it will be okay, you’ll get a routine and make friends and it will be fine.” Which I feel is kinda lame and not helpful.

How can I support him better? Being a teen seems so hard these days.
