@Gargron That sounds a pretty tough lifestyle - I don't think I'd cope with it well either. In that situation the best I can suggest is you put time in your diary to get out the home, to exercise, socialise, experience art/music or just chill outdoors or at a book library, keep to it and make sure all notifications and devices are off when you're chilling, resting or winding down listening to some music or reading a novel getting ready to sleep.
