Firstly, I'm not entirely sure if this is where this type of topic goes, so forgive me for that one :S
Second, I'm writing a book, and I wanted to include a poem in Gàidhlig in it. I have it written, I just need to make sure that the grammar is correct and that it's well written. I still have only a basic understanding of Gàidhlig so it would be appreciated if you guys would help me out

The poem itself is as follows:
M’anam, mo cridhe,
thoir leat uile a tha agam.
Caochailidh mi nam seasamh.
Fìrinn, saorsa, cothromachd,
fuilingidh iad seo gu brath.
And the meaning is intended to be:
My heart, my soul,
take all that I have.
I will die standing.
Truth, freedom, equality,
these shall endure forever.
I hope I haven't committed any egregious errors, but if I have, please point them out! Tapadh leibh!
