Edit: whoops, sorry, I thought that question was for me. I read carelessly . . . slinking away now...

Yes, I have succeeded! Long ago. Back in college the first time, in the 80s, my prof had as a project option a personal time management study as I described. It worked for me and I've used it over the years to revamp. Learning new habits has also helped. I always gets projects in on time, have never deferred exams, and feel very comfortable with deadlines. You just have to make priorities. It's obvious you have some challenges and changes to make - but after you do the home and food problems will become safe and reliable routines you are in control of. You just have to make it a priority for a while until they are set.

I've had plenty of panic. I prevent the chance of it with the above routines. I'm quite rigid in many ways. You are pushing yourself hard at school. When did things go wrong this term? When did you start to feel out of control? Analyze, and you can do better next time.
