"Life is what you make of it" shouldn't be a scary thing to you - it should be liberating.
Think about it - nothing you have to do, no goal you need to aspire to, no expectation you must conform to. You're totally free to do whatever you want, define your ;life however you want and do whatever you want with it. It's a great amount of responsibility to take the steering wheel in one's life, but it's what you and everyone should be doing.
Discover something that interests you - anything at all, no matter how small or silly - and grab onto that and start building your interest more. Learn new skills, attempt new hobbies - read a book, watch a film, go out and do something fun by yourself etc. etc.
It's your life and only you can create the meaning to it.
