COC Blood Mage Squish

I just respec'ed my EDC Lich into a COC spark comet Blood Mage and it feels way worse.
Did I do something wrong? This seems to be a very popular build to make and i just keep dying so easily.
The damage is fine, but I die so easily, especially in temple runs.
Here is my POE Ninja: https://poe.ninja/poe2/builds/vaal/character/calmbatman-7355/EssenceOfVall?i=0&search=class%3DBlood%2BMage%26skills%3DSpark%26name%3Dessence

Any suggestions?
