It is growing tougher for print designers, as everything has gone digital. I know older graphic designers having the same troubles because most of the openings require knowledge of HTML and CSS.
That's life though, as clients are spending more for websites, banners, and emails over print items. If you're unable to design for digital, then you'll be left behind.
I'd suggest you have an online portfolio, and get some kind of digital experiences under your belt. Try to pick up some freelance, do volunteer graphic design work for charities, and especially go to networking events.
