Summarize:

It's a good idea to keep yourself busy in the wake of a breakup. If you linger on bad feelings for too long, you may lash out towards others. To regulate your emotions, take up a new hobby or rediscover an old one. This can help you be a better person, as you'll be focusing on new, positive things rather than negative feelings. You can try to join a hobby where you meet new people. You may be in a better overall mood if you focus on starting fresh with new friends. You could, for example, take a cooking or painting class. If you're taking care of yourself, you're more likely to have the energy to manage your emotions. This will make you a better person in the aftermath of a breakup. Make sure you keep up with eating right, sleeping right, exercise, and personal hygiene. Don't try to do too much when you're feeling wounded emotionally. Especially in the days right after a breakup, it's okay to take time for yourself. Do not feel bad if you have to lessen your commitments for awhile. For example, say no to things more often. Don't agree to do extra favors for others or take on volunteer opportunities. You need time to recover. Skip one obligation during the week. For example, miss one meeting for your church's vestry. Instead, stay in and do something nice for yourself. It's a good idea to stay social after a breakup. This can help you remember that there are still people that value you, even if you're not in a romantic relationship. Make plans with friends from work or school. Invite an old friend out to coffee. Staying socially active after a breakup can really help you mend.
Take up a hobby. Practice basic self-care. Take it easy. Make plans with others.
