Jesus commands us to love as He has loved us. He is not talking about a feeling, the way love is usually treated in popular culture. He shows us what love is. It is difficult, and needs the Spirit's power. It often feels bad not good. Jesus shows us how to rise above feelings and to keep showing love in the way He deals with the hurt of Judas' betrayal. It's this agape love that marks out the church from all other societies.
