Im guessing the effects of his own shikai doesnt faze him then? Considerign that the shikai makes the strongest of people freeze in fear and watch the sword deliever their death.

It did. He felt fear as that thing came down towards him but he wanted to live, he wanted to fight, he couldn't afford to die no matter what. He had to overcome his fear to attain Bankai...it was the only way for him to survive and face his fear of dying before completing his goals in life.
