My future!

Now I'm sixteen years old but in 2 years I will probably stay at the University with some of my friends studing a career. 

Maybe I'll stay in Barcelona or in Girona but I don't know what I'm going to do. 

I like maths, physic and technology and for that I'm studing first of scientific batxillerat in Castelló, and I would like to do something related with that. 

A part, my family have got a company and if I will study something related with this work (some engineering), my futur will be secure, but for that I have got a lot of questions like these: 

- If the work won't like me?

- If there's no work?

- If,...if...if...?

Now there are a lot of questions inside my head that make me feel worried because I don't know what I'm going to do yet!
