PLEASE HELP HER I NEED TO KNOW

My teenage daugter who has an ex boyfriend that is obssed and will not leave her alone ,He waits outside of the house and she cant even go out . He has kidnapped her beat her.Ever since all thats happend she's bein under so much stress with everything just this last week she has had what appears to be seizures one lasted up to twenty minuties but when it happens she cant remeber anything about it, she was losing alot of hair when she was with him and he was abusing her and lately its falling out like crazy. How long are seizures,usally and does the person that has it not rember at all? Also can all the stress cause her to lose her hair?When she had what i think is seizures she looks like she dead she doesn't fail around but wben she starts to come out of it her eyes roll around and when she does come back she cryies which is not like her a all. Please i need to know what to do. Also the first time she had one of these she was foaming around her mouth her eyes where rolling around and then she looked like she passed out.HELP
