Like Khalil Bodhi says, it's more usual to get established with giving metta to yourself first.
Then when you are firmly established with that (maybe a few weeks or so) add on giving metta to people who you like and care for.
Then a few weeks (or days) later and you're good with that, add on sending metta to people you are neutral towards.
Then a few weeks later and you are solid with that, only then go to sending metta to people you have negative feelings towards.
It's a gradual thing. Don't try to jump in the deep end and send metta to people you don't like at first. It'll backfire and jam you up.
If you are the book-reading type, Lovingkindness by Sharon Salzberg is an excellent book about how to do it.
