Have I made the right decision?

Just think of the future, and whether you'd regret the decision you make in four years' time.

Basically, I have just returned to University for my second term, and after having a horrible experience during my first term having to move accommodation, I am feeling a little anxious about being back.

The thing is I love my course but I just feel positively miserable in terms of ;uni life'!. I am in a relationship and we have been together for 4 years and I just feel I sometimes would just give it all up so we can already start our lives together. But other days I have a clear head and I know why I'm here: get a degree, get a good job and have a happy life with my partner. But is 3 years of misery worth it?

I need some advice!
