I agree with Blue , Sit down and talk to them . Honestly no one LIKES to go inpatient myself included. But there are times when its a good thing.
As a fellow cutter I have gone inpatient due to it... It kept me safe and allowed for a faster than normal medication change. The longest I have ever been inpatient was 7 days by MY choice .. all the other times were only 3 days , because I went in voluntary admit.
I hope things improve for you and however this situation gets resolved the main thing is YOU STAYING SAFE
