How can I say in turkish: "Thankis for supporting me in such a difficult moment; you're the only one I can count on"

thank you all

sorry for the spelling mistakes ....Im a little sleepy right now

There are no Turkish characters unfortunately. I'm still trying to find the kind of keyboard in Turkish I would like using. Anyway here we go:

"Bana boyle zor bir zamanda destek oldugun icin tesekkurler. Guvenebilecegim bir tek sen varsin."

thank you so much
