So not i personally need support but someone who is really important to me went through some serious trauma and it got triggered and i've been watching her getting worse and worse for like a month. She sleeps less eats less and is constantly in some kind of state where she ignores people then tries to talk to them

When i talk to her she admits she is not well but she doesn't wabt to show that because she doesn't want to burden anyone else even tho i keep telling her that keeping up a fake smile is worseing it for herself and that she should be more selfish

Everytime i try to make her look better on things she responds hopeless and i just din't know what i can say to make her feel better. 

She just recently bought sleeping pills while i think it might help her i still think she should better visit a doctor but she refuses to see one (not because of prices healthcare here is covering all the costs), i think it's because of that hopelessness that she just can't bring herself to do anything. 

All i do for now is remind her that i'm here keep my notification sound on and long so that all she needs to do is wrote me one simple message in order to wake me up be next to her especially in social situations but all that is not really working and now i'm against a wall because i really want her to feel better ASAP

Any advice?
