CrazyJenner,
Is the heartbreak from the 4-month relationship ending? If so, I recommend spending some extra time working (whether it be a job, going back to school, joining a social club at church, helping a charity, cleaning the house, painting etc).
Taking a little "time out" will give your heart time to heal from the ended relationship before trying to start a new one. During those weeks, you will have time to understand WHAT went wrong, HOW you could have done things differently, and WHY the relationship ended so soon. This will help you later, so mistakes of yesterday are not repeated tomorrow (discovery of self).
It is by yesterday's failures, that we learn to create tomorrow's successes.
Blessings,
