Hi Paige. Your situation with your daughter sounds very serious.
You have other people in your family that need your help and attention too. But in my opinion put your daughter's needs first. Let her know how important she is to you. Also, make sure that she is allowed to make day to day decisions. Check that she is ok financially.
You or your daughter can phone the Samaritans for advice on 116 123.
Encourage your daughter to speak to other people such as friends and relatives if possible.
Don't leave her on her own for long periods of time.
