I got laid off from a job I hated--one of the most boring jobs ever. Anyways, in a period of 3-4 months, I got another job and got laid off again in 2 months, I moved to another apt, broke up with boyfriend, got sued by ex-employer, moved again to another apt (landlord asked me to move out of her house), then find out my dad have lung cancer and is dying--that was the worst blow of all. 
I became depressed--sleep all the time and later had insomnia. I didn't eat much and lost 25 lbs. I felt like a zombie with no energy for several months....that was the worst time in my life.
I went to counseling a few months later and my therapist explained all the signs of depression and grieving such as insomnia, etc.
