Fill your time with things you enjoy, whatever that might be .... movies, games, friends, sports, landscaping, kite flying, sky diving... Do these things on your own or with friends or people who have interests in the same things. This should make you active in your life and less concerned with what she's doing or what will happen to her. Life is for living, not watching others live it.
