Morgana tortured Gwen until she broke her -- she clearly has succeeded. She used the mandrake roots -- lots of them to trick her to believing the hallucinations she was having were real. And she then used kindness to brainwash her, and also by making Gwen feel sorry for her by sharing the experience she had when she was in chains for two years some dark hole. I think the whole experience was overwhelming for Gwen.

I hope that Merlin uses his powers to help Gwen see that she was brainwashed. I think though once she realizes what has happened, and that she almost kills her beloved Arthur she's going to want to take her life. This is the scenario that's shown in one of the pictures I seen either on this sight or another. Arthur is in the water perhaps talking to Gwen trying to convince or save her.
