Alma, the only way to recover from your breakup is to "throw yourself" into your work or hobby or family/friends' activities and so on!
Keep your mind BUSY so that you won't have to think about "bad things" or have the time to conjure up "bad memories."
Turn off the radio (so that you stop hearing those "love songs" that you and the partner had a relationship) and put in your "HAPPY CD/mp3 songs" instead.
Schedule events in the next few days like a hike or meeting up with a friend/family member at a restaurant/mall/park or go on a trip somewhere.
Spend more time with your loved ones and please talk to someone when you are feeling down. It's good to verbalize your problems rather than keeping them inside you.
If things get worse, please see a counselor/therapist for help.
Good luck, Alma, and let me know how you're doing.
