Increase Resiliency when faced with new challenges: Think of all other past challenges you've gone through and think, "oh, if I've gotten past those, then I can do this!".
Cope with loss: Instead of focusing on the fact that the lost one is gone, instead think of all of the good memories you had with them to leave a smile on your face.
Maintain positive self concept: Make a mental list of all of the good things about yourself, keep yourself upbeat and happy, never let your optimism be defeated!
