Pay attention to what you need in any given moment and speak up to express your needs. Honor what you believe to be right and best for you even though it may be different from what your ex or others want. Say "no" without guilt or angst as a way of honoring what is right for you.
Stick to a routine. A divorce or relationship breakup can disrupt almost every area of your life, amplifying feelings of stress, uncertainty, and chaos. Getting back to a regular routine can provide a comforting sense of structure and normalcy.
Take a time out. Try not to make any major decisions in the first few months after a separation or divorce, like starting a new job or moving to a new city. If you can, wait until you’re feeling less emotional so that you can make better decisions.
Avoid using alcohol, drugs, or food to cope. When you’re in the middle of a breakup, you may be tempted to do anything to relieve your feelings of pain and loneliness. But using alcohol, drugs, or food as an escape is unhealthy and destructive in the long run. It’s essential to find healthier ways of coping with painful feelings.
Explore new interests. A divorce or breakup is a beginning as well as an end. Take the opportunity to explore new interests and activities. Pursuing fun, new activities gives you a chance to enjoy life in the here-and-now, rather than dwelling on the past.
