Phrasing for one current fellowship and one previous fellowship I'm receiving support from Fellowship X, and previously I received support from Fellowship Y. I want to write on my website


  I am fortunate to be supported by Fellowship X. Previously, I was supported by Fellowship Y.


But it might seem that I'm not grateful for Y. If I write


  I am fortunate to be supported by Fellowship X and Y.


it is not accurate, because I'm no longer supported by Y. Is there an elegant way to phrase this?
You don't need to wax about how grateful you are if you're just providing information---note that that can also come across as bragging.

Just keep it simple and to the facts:


  I am currently supported by X (20XX-present), and was also previously supported by Y (20YY-20ZZ).
