I didn't want to ask this

Yes I did, it's a sin I struggle with , I know it's mortal

 

Re: Condition 3 .. In spite of thinking/believing that you've actually fulfilled that 3rd condition (for, it's easier said than actually done) please show us how you fullfilled that condition?

 

I knew I was breaking God's law. Am i well and truly damned ?

 

Knowing you're breaking God's Law fulfills Condition Number 2; NOT Condition 3.
Time for another confession, eh?

 

Eternal God, in whom mercy is endless and the treasury of compassion inexhaustible, look kindly upon us and increase Your mercy in us, that in difficult moments we might not despair nor become despondent, but with great confidence submit ourselves to Your holy will, which is Love and Mercy itself.

This is the closing prayer to the Divine Mercy chaplet.
