you have said everything that you should, but its a bit jumbled up, how does this sound?

Every day is different due to my condition being so variable. Depending on how well I slept I wake up between 7 and 10 am. On a good day (2-4 days a week) I make breakfast and attend an appointment if i have one, watch a show on TV , help my son with his school work, eat dinner and retire to bed around 9pm. When my condition is bad (usually 3 or 4 days a week) I wake up around 3 or 4 am, stay awake for a couple of hours then sleep till around 10am unable to leave the house I phone mum about 8 times during the day. She helps me take care of my son and clean the house. At least once a week I am unable to sleep at all due to panic attacks and voices in my head which means I am awake for two days solid which exhausts me and makes me even more depresses and anxious.
my food intake is dependent on my state of mind, I overeat when I am depressed (lunch then lots of snacks), undereat when anxious or have psychotic symptoms (no lunch, maybe a snack).

by saying mum helps you care for your son on bad days proves you have things in place for these days. I would be much more concerned if you had not mentioned how you cope with him on bad days.
