Yes, including me, your 30-something year old self who you're probably going to ignore just like every other adult.
No matter how much your mother criticizes you, do the best that you can for you, not her. She can never be satisfied and is going to create a hyper-critical voice inside your head that sparks a self-loathing that will stop you from doing many things, exploring many relationships, and generally being open to healthy relationships.
Being alone isn't a terrible thing although it may feel that way.
In eight years you should go to college instead of taking a year or two off. Those few years turn into eighteen and you'll end up going to community college instead of realizing your true potential.
Also, although the wanderlust will be strong, pick a place and stay there for a few years. Believe me, every place you'll go is exactly the same as the last because you are you no matter where you go. You'll be a lot happier staying in one place for a while because you'll build deeper relationships with people whether or not you try.
