user3551: I find it very difficult to practice metta because i can't find anyone who has been a benefactor.I don't know a lot of people.Most people i know i find it very difficult to send metta to as a benefactor as their either very dear to me or downright hostile.Can i just imagine a benefactor i never had .Or use a dead person, as my auntie was very kind to me but she's deceased now.
How can i practice metta without a benefactor? How can i find a benefactor to practice metta to?

user295: A benefactor is not necessary. You can pratice Metta using categories which is the way to pratice Metta without a benefactors. E.g. All beings, all being in front of me, etc. There are 22 such categories in Paisambhidā-Magga. 
One objective of Metta Bhavana is to dissolve ego and break down perception and this is my friend and someone is my fore. If some one is better off than you chances is there is some inner resistance to practice Metta or Muditha towards him. If you believe someone has wronged you then the chances are that it will be difficult to spread Metta.
As you progress try to break down negative perception you have build about people. Also look at the impact on other aggregates as you practice Metta. Look at the sensations as you make thoughts off Metta.

user18: You don't need a benefactor to practice that type of metta; you just need someone who is dear to you;  it just shouldn't be someone you could potentially desire sexually, or whom you are partial towards, like your children. 
The stages, according to the Visuddhimagga are as follows:

cultivate metta towards yourself (useless, but a good example)
cultivate metta towards someone you hold dear
cultivate metta towards a neutral party
cultivate metta towards someone you dislike (optional, only for those who have such a person)

Having someone dear to you seems important, as there is no advice given for what to do if such a person does not exist. Ostensibly, you could skip that step and try to immediately cultivate metta towards a neutral party, but the dear one is useful for returning to when difficulty arises with the other objects.
Alternatively, you could try cultivating metta in order of proximity; may I be happy, may all beings in this room be happy, this building, this city, this country, this world, the universe. Also, by direction; may all beings to the East be happy, etc. Or finally, by class: may all women be happy, men, animals, angels, etc.

As he says, 

"Mettā can also be developed towards any other person deserving of affection and respect, if not towards your teacher, grand-parents, mother, father and so on."
