My sister is in her early 20s, she suffers from severe depression &amp; anxiety. As well as a load of other stuff I'm not aware of.

We haven't lived together or been that close for 10-15 years.

Recently she has been severely self harming, slashing her legs open and requiring extensive treatment.

Mental health "services" have been to see her multiple times. They have prescribed her medication which don't work.

She shows no signs of endangering others.

She does not work, she did really well in school but hasn't done anything since she left. 

Preferring to stay home, just going to the shops is extremely stressful for her.

Both me and our older brother have fairly bad anxiety but we've grown to kinda suppress it (I still get it constantly but I try my best to power through). This was by getting full-time jobs in customer service.

Although I know about this stuff, she doesn't know I do. Mental health "services" have branded her psychotic. She suffers from hallucinations.

I firmly believe her anxiety and depression have crippled her so much she's developed these, we don't come from a good background at all.

How can I approach her about this?

She needs some self-confidence, being stuck in, afraid to go out must be horrifying to live with. Imagine this for 10+ years.

She loves make-up, clothing, art etc. She's good-looking and could easily be a model. I need to portray this to her but have no idea how to approach it :S
