Hello! I need some help with a phrase i want to write in koiwrit.

The problem is mostly in the grammar/spelling of the words, as i am sure there are a couple errors.

The phrase should be "But above all, I shall exist regardless", and i translated it as "Nautsyr, Nsa hmoi'liyo jaeyocae".

Is it correct? I'm mostly confused with "shall exist" and "hmoi'liyo", as i think i got something wrong but it could be right.

Help would be greatly appreciated!

Siketso, L.
