I was in college in 1980 to 1984 (actually, 1983. graduated 1/2 semester early), so trying to remember might put a strain on the brain. But mostly I liked it. But I always liked school. I was always a loner (so not making a whole lot of friends does not come as a surprise). I will say that it has not done a thing for me. I was unable to find a job to put my B.S. to use even though I graduated with honors.
So the point is 1) everyone is different. and 2) I am truely sorry it was unpleasant for you.
