There’s certainly plausible reason to wonder about it. Consider how many women take it, for many many years. Many women go through multiple different types of pills due to the effects certain pills will have on their body, from weight gain to period frequency.

You do that for 5, 10, 15…20 years…it’s reasonable to wonder what it will do longer term.

At the same time, as you age and have older friend groups it’s hard not to notice a correlation between the friends you have who never took birth control or minimally took it who also have no anxiety issues and those that don’t.

Maybe it could be something else but IMO it warrants further study.
