Being the only junior on a team of all seniors is lonelier than I expected

Six seniors, then me. Everyone around me has 8+ years in, and most days that's genuinely great — I'm surrounded by people who know things. But there's a specific kind of isolation nobody mentioned when I took the role.

There's no one at my level. No peer to turn to and go "wait, you were confused by that too?" When I don't understand something, I can't tell if it's a normal gap or a me-being-slow gap, because I've got no baseline to measure against. The seniors are kind about it, but they cleared this stuff so long ago that a lot of it is invisible to them now.

If you've been the lone junior on a senior-heavy team, what got you through the stretch before you found people at your level? I think I mostly miss having someone to be confused alongside.
