Welcome Struggling.
You are wise to seek the support of this group. There is so much compassion on the network and a wealth of information.
It is exhausting to be where you are with your DD.
We have recently had to set some very clear limitations with our DD36 due to refusal to get help (therapy, recovery, Rx meds). We have removed all financial support and she is homeless because no person is willing to take her in.
As present she is in the local shelter and today entered their faith based recovery program. As we pointed out to her, she is free to leave and go wherever she wants, her choice. She has choices and so do we. Ours is to not support her lifestyle.
You have the right to say 'no', the right to protect your home, the right to not be verbally abused, and a host of other rights.
May I suggest embracing the time your daughter is away as a 'relationship vacation'? Sometimes it is OK to step back and take a breather. Maybe spend some quality time with the other daughter?
Warmly.
