When you breakup with your partner you go through a range of intense emotions, whether you have talked out of a relationship and given serious consideration to the decision, or if you were simply dumped you will go through a range of few different emotions and it is hard to overcome these many emotions at a time and you have to do the right things to get yourself out of that situation because the emotions would take a toll on your mental health and physical appearance as well, we usually go into a passive attitude and let out emotions control us rather you should be very proactive and fear having a bad routine for a very long time, handling your emotions post breakup with a positive attitude is key and there are a few things that help you.
Don’t hold every emotion inside, don’t be that person who refuses to cry or talk to a person because that could be detrimental, if you are that sort of a person in everyday routine then its fine but don’t go into that shell once you breakup because that will cause more damage to your personality than you can ever imagine so it is better to allow yourself to grieve and when you feel like you need someone to talk to then you should, do not hold onto your emotions for far too long within you.
It is quite common to build negative thought patterns and connect all the dots and create an extremely negative vibe not just about what happened but about the future itself, you need to avoid this from happening and focus on the brighter side of things, work on yourself, mentally and physically and look ahead rather than dwelling upon your past.
