How does one deal with the 'fear of rebirth'?

At times when even Stream Entry seems implausible let alone Nirvana how does one deal with the fear of rebirth. Rebirth would mean over again; disappointment after disappointment and after horrendous ordeal of life coming to understand the Buddhas teaching and learning everything all over again. I have dealt with the five hindrances to meditation, but this fear of failure in this life has taken its place. Its not death but rebirth that I have developed aversion towards. How do I address this? How do I get equianimous towards this idea?
