What do these mean?
1. I miss high school life. ('high school life' in general?)
2. I miss my high school life. (my high school life?)
Does it matter which one I use? What's the point of having 'my'?
I think you are right on this. I see #1 as a gerenal idea about life in high school. Number two is more of an emphatic use that expresses those good old days, and I just missed my school much.
1. I just missed my school (very) much. (Was 'very' omitted here? What does it mean without 'very' and with 'very'?)
I just missed my school much.
