Fear of future

I am a computer science student in 2nd yr, 18

I am really scared for my future.

The job market, everything is so bad right now

All these negative thoughts.

I won't succeed?

I won't get a job?

Would I live a miserable life?

All these thoughts just keep going in my mind.

I am not able to focus on anything, all these negative thoughts are not going away from my mind.

How do I remove this fear of Failure/fear of future?
