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?
