Failed classes

This year I've failed my second semester classes because of my battle with my depression. I couldn't get out of bed to get to school even though the classes I had were electives and easy. Because of this I will be graduating a semester late, which I personally am fine with.

However, my friends constantly bug me over the fact I failed my classes acting as if I failed them because I wasn't smart enough.

It's hard to talk to them about things like my depression so I haven't because I feel like they'd judge me even harder for that.
