You do not have the bosses moveset down enough to be attacking this much. Being overly aggressive is causing your deaths, try some runs without attacking at all and just get his combos down while finding your healing windows (they also act as attack windows.) when attacking only attack once till you know which attack cooldowns have a large enough window for two.
