Hello Iona
Exam time can bring a lot of mixed feelings. Especially the feeling to start dating, needing a support romantic structure, procrastinating and family issues.Which can be very distracting. Feeling worthless is often a low self esteem issue and judging your body weight. It is best to start toning your body by running or joining the gym or play sport like Basketball (something that will make you sweat o lot) and working on improving your Self Esteem ( that long term). For the procrastinating part you need to tell yourself that it is time to study and find a quiet place (room) and study for 45min take a 15 min break and another 45 min study break and last 45min study every day ... or 6day a week you will rock your exams . "Look for How to Study" Guide I used this method in High School and in College it worked out.
