You can get divorced and keep on keeping on, being the same as ever, accepting life as it is OR you can approach divorce as an opportunity to re-evaluate your life - who you are, what matters to you and how you live your life.
Re-evaluating your life doesn't happen by accident. It is a conscious journey starting with an understanding, or a feeling that how you've been living your life somehow isn't being true to yourself. Then comes a period of self-discovery, getting reacquainted with yourself. Next comes the hard work of redefining your many hats - parent, professional, friend, lover - aligning yourself more closely with the new you.
It's demanding work but it can be immensely rewarding. Try imagining yourself in five years time - what does happy look like and what would it take to feel that? If you don't know where to start, then divorce coaching may help.
