Should I be at university?

Yes really should. It would keep you occupied and you will find many friends. You can always have fun, but if I was you I would worry about my education and get situated then you can have all the fun you want with YOUR OWN MONEY. If I were you i would not wait until I was older to go back I would go now while I still have an active memory and brain.it gets harder when you get older so go now. Do something positive with your life and CONGRATS on your new journey in life. And remember when you feel like your alone you always have Jesus.
