Hope

defininition from wikipedia in english begin quote: Hope is a belief in a positive outcome related to events and circumstances in one's life. Hope is the feeling that what is wanted can be had or that events will turn out for the best. To hope is to wish for something with the expectation of the wish being fulfilled, a key condition of unrequited love. Hopefulness is somewhat different from optimism in that hope is an emotional state, whereas optimism is a conclusion reached through a deliberate thought pattern that leads to a positive attitude.

Whereas unrequited love even though it can be an aspect of hope is something actually different. Unrequited love appears to affect about 98% of all humans at some time during their lives so in this sense it is an almost universal experience.

Wikipedia lists some poems about unrequited love. Since I found them interesting I thought I would share them. The first in "Anacreontiques" by Abraham Cowley, the second by Robert Burns called "Anna"

Begin quote from wikipedia

"A mighty pain to love it is,
And 'tis a pain that pain to miss
But of all pains, the greatest pain
It is to love, but to love in vain."

next poem:

"Anna, thy charms my bosom fire,
And waste my soul with care:
But ah! how bootless to admire,
When fated to despair!

Yet in thy presence, lovely Fair,
To hope may be forgiven:
For sure 'twere impious to despair
So much in sight of heaven."

continue quote:

As the literary selections suggest, the inability to express and fulfill emotional needs may lead to feeling such as depression, low self esteem, anxiety and rapid mood swings between depression and euphoria. A universal feeling, by some estimates affecting 98% of all people during their lifetimes, unrequited love has naturally been a frequent subject in popular culture."
