These are some of the biggest reason why I feel I wouldn't be able to go anywhere long distance alone especially if it will be out of India.

1) I usually get scared when the flight takes of and also during landing. Usually I hold my parents hand while take off but if I am alone then whose hand would I hold when scared during the take off? So I am scared about it.
2) Usually when I go out in my city Bangalore, usually my parents and mom's friend and her family will be with me. Even when we go to Siliguri and Falakata my grandpas will be with me when we go out. So if go somewhere alone especially out of India I would be all alone and might get lost somewhere too.
3) If I go somewhere I would have to be in a room all alone. I have never been in any house alone so I would be scared at night that what if some ghost scare me or some robbers enter.
4) I can't cook anything so how would I manage to eat when alone.
5) I might feel lonely too all alone being somewhere unless I make some friends which will definitely take time for me as I am an introvert person in real life.
