How to get a diagnosis????

Hey so im not diagnosed so I might be allistic (sorry for encroaching I don’t mean to distrurb to group I just really need advice) but i think I might be autistic.

For context im female and a teen and I’ve struggled socially for years and I uncomfortably relate to some of the tells for female autism,looking back I was a weird kid too,

Do you guys have any idea how to approach my  Indian parents into getting me a diagnosis cause im just so tired of feeling like an alien pretending to human
