is it normal to worry about my future like this?

Worry/fear is alot like snake venom. The more you think about it the faster your heart beats and the more quickly the venom pervades your system. By worrying for his life the snake victim is ending it.

Worry is much the same. It cripples you but the less you think about it, the less apparent it becomes.

So drop the worry and make a year plan for accomplishing your goals. Or fall into apathy.
