My son's girlfriend started cutting herself at the age of 15. She broke off an apprenticeship, then started on the drugs and alcohol. I persuaded her to come to "Suchtberatung" with me, where the pyschologist decided she was suicidal.

At 17 she left home to be with my son and did not go home to her parents house for more than a year.

Only when her mother, who was devastated by the situation, started going to a pyschologist herself and put her own problems in order did the daughter stop cutting herself. ( The mother was very controlling and a perfectionist who was very critical and gave her daughter the feeling she could do nothing right).

At the age of 21 now things are beginning to fall into place and she has stopped the drugs and drinking and has an apprenticeship of her own choice starting next September.

I really DO think you need professional help or advice. Good luck with your daughter.
