Earlier this week, Chelsea captain Millie Bright withdrew from the England squad for their upcoming Nations League matches to take an extended break and allow a period of recovery.
England welcome Portugal to Wembley on Friday (19:45 BST), before travelling to Barcelona to face Spain on Tuesday (18:00 BST).
Bright, 31, who led Chelsea to a unbeaten domestic season and won the Treble, said she is “mentally and physically” at her limits and needs a break.
Wiegman did not confirm if she will return in time for the Euros but says she hopes Bright can “take the time that will help her settle again in time”.
“She has to take care of herself. We are in conversations and I don’t know where that gets to,” added Wiegman.
“We’ll stay in contact and I hope she feels better soon, but I don’t know that yet at the moment.
“We have people around who can give that support. The demands on the game, on and off the pitch, has increased a lot. We have to adapt and that’s not always easy.”
Williamson, who started every game alongside Bright at Euro 2022, said it was a “brave thing” for the Chelsea defender to speak out about.
“I think for anybody to speak out about mental health is a brave thing to do. I think it encourages other people to do the same,” said Williamson.
“She’s leading by example. I’ve given Millie a bit of space, when somebody is in that head space. But naturally, any support that she needs and anything that she needs from the team, we will be there to give it to her.”
