I know how it all feels.. You must be feeling like a stranger with everyone... You just feel like everything has changed and it just seems weird..
But you know what? you will become better than before soon.. It's just a new step in your life and once you get used to it you will just find that this experience is the one that is gonna create you and make you the person you had to be... Life is just a combination of experiences, a small one gets added to a bigger one and that makes You. Don't ever be scared by the cold welcome of adulthood just have hope and move on
