Hello can anyone give me any constructive advice please.
My daughter is almost 18 and has a boyfiend of 26 who has a son he sees at weekends this boyfriend is a very bad influence on my daughter.I first discovered he was buying her diet pills after discovering them tidying her room.This did not go down well as she insisted i had invaded her privacy.I advised her that the pills were not a good idea and that she was still growing etc.. and she was absoloutely fine.He has been calling her fat though she is only a size 12, she says he says this in jest.yet every time he is at my home all they ever talk about is calories,protein drinks etc..which i am not happy about at all, she now notes everything she eats down and texts him the details daily.He has stopped her eating or drinking salt sugar coffee fruit as he insists they are all bad for her.She will no longer eat meat butter and lots more.She eats very little and is now staying with him at weekends.She comes home shattered and it is her A level exams time after the easter break.He is very controlling but she doesnt see this as he is her first boyfriend and is in love with him.He has even smiled when i have voiced any dissaproval and had the cheek to say to me she is old enough to make her own mind up. Throughout the last 6 months she has been going out with him she eats little and less each day she goes to the gym far too much she is constantly tired and her hands and feet have been looking grey and felt cold.last weekend she came home from his house tired and was on her laptop for a few minutes before she was going to go to bed.Her hands looked like they were dirty or had been rubbed by a newspaper then i looked closer and picked her hands up they were black and very cold she said they were numb i looked at her feet which were not quite as bad but were very grey with a tinge of purple.I called the nhs helpline and they asked if she had cold symptoms or breathing difficulties.She didnt or so i thought as she had not been home long.The hospital wanted her to go in.But she wouldnt go no matter what i said.The doctor on the phone said she could lose her fingers or her hands that it was quite bad.She said she would take her chance that she was not going to hospital and that she was fine.My daughter and 12 of her friends have just gone on holiday for the week.her boyfriend invited himself along with them last minute.They are all going their seperate ways to university soon so i was not happy that he was joining them.All through the week before she left for her holiday her hands were bad i tried to get her to go the doctors if not the hospital but she refused.I am very worried.What can i do.I am worried for her health i am worried about her controlling boyfriend and her poor eating habits fashioned by her boyfriend.Even when an occassion has come up and we have had a little halloween party for eg she and her frineds usually dress up(fancy dress) but since he thought it was immature and silly the next fancy dress that came up she and him were the only ones that didnt dress up.This is not like her as i know she loves it but she feels all grown up being the only one of her friends to have a boyfriend with a child who drives a car and has a job.i am so concerned.Does anyone have any suggestions I have tried sitting and talking to her but she doesnt want to hear it.I know she is not well but i feel helpless.Now she has sensed i dont like her boyfriend it has made her want to be with him and defend him more.I should have expected this but it is difficult when i see the damage he is doing.As for her hands she insists she is fine Help.
