Sorry to come late to this.

I'm still nutting over the always/never bit, but for blessings vs losses part, I would suggest the following pair of opposites:

suáilcí and duáilcí

Suáilce is sometimes translated "blessing" and duáilce is its opposite, sometimes translated "defect, joylessness, unhappiness".

Perhaps:

Suáilcí i gcónaí gan duáilcí riamh
