I'm a 17 year old,I live in London tottenham hackney all my life!

On 14th april my mommy passed away due to heart attack and she was my single parent!

I want to leave London with her best friend and move to India

The trouble is I turn 18 on 2nd november and I wanna know if I can leave london as soon as possibe or should I wait till the date!

Is there any way that I can go with my mommy's friend as a minor instead of waiting!!

I want to leave from heathrow airport! THANXXX
