I believe all students will feel this way at some point, i did too and i know
exactly how you feel! Ok well at least a 98% as we all are different but... I can so much understand how it is like. Studying something and doing essays that you think are pointless and dont give you anything more than a piece of paper at the end that others might already have and perhaps found no good use for it or didnt gave them anything extra. However it does gives you an advantage and maybe a big one to start your life. You might not feel it now but being in the university doing all these course work, have no time for much, dealing with deadlines all the time is stressful and gives you a big headache BUT believe me it so worth it. You are growing as a person , your mind gets stronger and if you are a good person you become better.
When you go into employment you will see the degree that you have shows your employer you have knowledge on a subject but further more shows them you have committed to something and finished it. It is like
a life experience you get by studying and others get by working for years and years but you have specialized into something that makes you highly employable. This is what the employers actually want to see. Also on the way of your employment you will learn more, get more experience and from that ..sky is the limit.
Btw degrees like yours are very very versatile. If you dont know yet what you want to do in life (i am 30 and i have trouble with this too... yeah funny i know but actually it's not :redface
you can take your degree and apply it in what you want. You can start something yours you can make a twist in your career to be happier , oh so many things you will find on the way.
