Good Day..... She may need counselling to express her emotions. After which we can decide whether to go for any specific treatment or not. If need any assistance kindly get in touch..

Good day..I can understand your concern.  People with such hesitation,  you can't force them. Better to start with Couselling sessions, which will help them to open up and  ventilate their emotions. In that process, we can identify if there is any need for medicine and recommend doctor consultation accordingly. Be positive.  Feel free to reach me for further assistance.

You are trying to change someone's else's character. Which is beyond your limit. Rather work on yourself. She may get inspired by you. The best way to change your surroundings response in to change yourself. The surrounding will change itself. Think whqt advice you would have given to your frd . Don't think she is your mother.
