I think you're heading for burnout, Tom, that's if you're not already there. It's impossible to give, give, give every day and not lose a little bit of yourself along the way. It's winter, it's cold and miserable and your job is certainly harder than usual at the moment. Your post made me want to give you a great big hug. Who's looking after you? Are you doing much in your time off apart from sleeping? Are you taking care of yourself? I hate to sound like a mother but I worry that you're going to end up in a big heap with no one to pick you up. If you need time out - take it. If you need to quit and get a job in Sainsburys - do it. Your mental and physical health are more important than anything else. No job is worth losing yourself.
