Her seyim benim.  Iyiki varsin.

Thank you.

Gina

You are my everything. It´s a good thing you exist (It´s good you´re existing).

I can´t modify my post, so I´m just going to add a note, I think the meaning of "iyi ki varsin" can be better conveyed by "thank you for being there" - it´s not the exact translation, but I think you will find that sentiment expressed that way in English more often than "it´s good you exist".

Opps, I needed to modify again, sorry for the multiple posts.

Just wanted to add that, "you are" in the first stentence, is implied, it´s not directly stated in the sentence.

Hopefully a native/more experienced learner will correct it if I´m off track.

Thanks so much for your reply..
