It might take a few sacrifices, but it can be done.
I've downsized my life, so to speak. Had some health issues including depression so can't work full-time, so currently studying full-time (which is really part-time hours compared to the 40+ hr week I used to work) and left the rat race to live in a country town which is quieter and much cheaper to live in.
I don't know your circumstances and I wouldn't presume to tell you how to live your own life, but I do recommend downsizing your life if your current lifestyle is seriously affecting your physical or emotional health.
