Hi 
StressedOutDaily I'm sorry to hear, that is a tough situation, the unknown of where it's going is scary after the recent calm. You are doing all the right things SOD, keep building your knowledge, practicing your skills, as 
Lollypop often says work on your core relationship, LP is also a master of re-do's, eg your DEARMAN when the coast is calm. What is your T suggesting by 'a higher level of care'?
Also told me she is not putting up with us and stupid concequences any more 
 What does your DD mean by this. Only the other day I was talking to my 30DD about an issue with our neighbours (she's been through DBT) and she called me out and said 'you need to let them experience the consequences of their actions!' I was like WOW...… there is hope SOD   As as 
Stampingt1 says it is one step forward one back..two forward.  It's not a linear journey, so when your heart is hurting, you feel defeated keep in mind that recent calm period you've had, as that is a breakthrough.
How's today been?
Big hugs to you dear SOD   us parents never give up.
