seni herşeyden kıskanırım

Is it about jealousy or envy?

 I Think it means

I envy you more than anything

but wait

Thanks deli!

PLEASE could some native speaker look at it, as there is such siggnificant difference in the meaning.....

I envy you from everything.

 and what means the answer on the sentence above...

Sen siz olmaz

"it can´t be without you"

Many thanks Scalpel
