Trouble with a sentence 状況を変えてくれるのはいつだってあなたのその気持ちだってこと


I came across a line in a manga and I'm not sure how I should translate it to
sound good. This is the sentence:  

> 状況を変えてくれるのはいつだってあなたのその気持ちだってこと

And here is my attempt to translate it:

> It's your feelings that can always change the circumstances (around you).

I really don't know if it sounds alright like this, something must be off.
Also, isn't いつだって similar to いつも?  
Or does it have another nuance?  
Please, I hope someone can help me out with this in any way. Thank you in
advance!

EDIT: For context, this sentence is said by a girl (older) to another girl who
is younger, if that helps.




Without more context, I don't know what kind of 状況 they are talking about, and
I have no idea what あなたのその気持ち ("that feelings of you") refers to. Please
always include at least what その ("it/that") refers to when you try to describe
the context :)

Anyway, since 状況 is used with 変えて **くれる** , probably she's talking about her
own 状況. The literal translation would be:

> 状況を変えてくれるのはいつだってあなたのその気持ちだってこと  
>  It's **always** your feelings that change the circumstances (around **me**
> ).

In other words, "your" feelings are affecting the speaker in some favorable
manner.

This should be correct only in say, 80% of the cases. Other translation will
be possible depending on the context.
