Today is another day. You don't need world changing plans or things, at least not ones that will happen in a day, or a week. For a lot of people it'll be a painful day after, but for others, it won't even be a new year on the calendar they follow. Five days til Christmas if you're an Orthodox Christian.
So try to identify what is good in you, and play to it. Look to what's bad, and try to minimize it. Look to what you can do for others. Don't pick details, pick directions. Do something you enjoy today, and try to do something others will enjoy.
It's really difficult on the edge of full scale adulting. You have the ideas, but if you are in the average family, you may not have the means to do as you hope. Yet. If I look at where I was at 16, where I was at 18 and who I was at 20 - 16 year old me would have been shocked at how life opened up and blossomed. Don't close your mind and don't let depression wear you down. Spring's coming.
