I found this quote to be very helpful, and I hope you like it too:
"The thing about life
is that you must survive.
Life is going to be difficult,
and dreadful things will happen.
What you do is move along,
get on with it, and be tough.
Not in the sense of being mean to others,
but being tough with yourself and
making a deadly effort not to be defeated."
- Katharine Hepburn
