tedinkyyy, it's almost right! I hope you don't mind I corrected some points, but your Slovene is great
Domovina
Homeland
Žalost mene, premaguje
Sadness is defeating me
ker zapustil bom svoj dom
Because I'm going to leave my home
šel bom daleč v kraje tuje
I'm going far away to places foreign
več nazaj, prišel nebom
I'm not going to come back again
Domovina, Domovina
Homeland, Homeland
zbogom zbogom, zadnji krat
goodbye, goodbye for the last time
bog
ve k'tera, bo ravnina
God knows which field
grob dajala, mi enkrat.
will give me a grave once
Starši ostanite zdravi
Parents, remain healthy
spomnite, se kaj na me
remember me sometimes
saj na vas, bo tu v daljavi
because of you, here in the distance
moje
mislilo srce
my heart will think.
Domovina, Domovina…
Homeland, Homeland
Zvezde ki ste, mi blescale
You stars that shone for me
ko sem srecen vasoval
when I was happy flirting*
ve me boste spremljevale
you will accompany me
ko v
tujini bom samval.
when I will be alone in a foreign land
Domovina, Domovina…
Homeland, Homeland
* vasovanje... this is hard to explain, it's like a village "ritual"... basically teenage boys (18 of age) go sing and charm girls under their windows at night

It's not common anymore, except in really traditional places.
Hope you don't mind me posting late, I just love translating
