My sister isn't well... Help?

My sister is 26 & she felt suicidal the other day so went to hospital and saw a mental health nurse and then came home, she is waiting for the details to go through to a mental health team and go through to our doctor also. But she needs help ASAP. She spends all day in bed, not eating, cutting herself, feeling down. So my family sent an email to our doctor to explain and he is phoning up tomorrow but what help can he offer her?
