Tradução de "It drains me''

Good afternoon guys!
I was watching a TV Show a few minutes ago and I saw the following expression: "It drains me". She was an old british lady saying that she can't wear lilac dresses because "it drains her". May someone explain me this? I've got intrigued because I haven't found any similar uses on the web.
Thank you so much! Forgive my grammar mistakes, please.

Perhaps by that she meant "it depresses me". Or perhaps it depresses her in the sense that she feels like crap.
