I don't know what other contributors you are talking about. If you're referring to abusing other substances, no I haven't done anything else.

Last year when I failed 2 courses, my first time ever failing any school. Was because I took a class higher than I was ready to work for, and I was sick for almost 3 months. I almost died from an allergic reaction.

This year I'm failing almost all of my courses because I'm missing too much school. I'm starting to go again these past few weeks because I want to succeed. But it's starting to get really hard to motivate myself.
