Especially when you are divorced you are hyper sensitive any song, seeing couples (happy), photographs of you as a couple can hurt you badly and severely so try to get rid of all the materialistic things that belonged to you and your former spouse. Start Yoga which will help you in calming down and while you are going through a bad patch avoid/ignore his/her phone calls all the time before/after the divorce, never start on some sort of an addiction other wise you will be hooked on to it for life, become optimistic find a reason behind what ever happened this way you will not feel as if you were rejected it will be the other way round. Consider the break up as a necessary step in your life because you deserve the best and it was about time to say “I have had enough now”. And don’t let anyone bring up the topic of your past and tell your best friend to stop you if you talk about your past.
