Thank you for contacting JustAnswer.
I am sorry to hear about the problems you are experiencing with your daughter It sounds as if your daughter may be avoiding facing her responsibilities and consequences of her actions. She may also be trying to avoid facing her feelings and may not be able to feel them in a safe way. While you can't control what your daughter does, you can be very clear with her that you love her, you are concerned about her, and that you believe that she has needs to take responsibility for her behaviors and choices. A family meeting in which you calmly discuss specific house rules and the consequences for breaking them would be important. It is crucial that you come up with consequences that you are able to enforce since otherwise these rules will have no impact on her. If this is not effective, then family therapy could be a requirement of her continuing to reside in your home. This could give you a safe place to work on the issues that are problems. You may also want to pick your battles about what is important for you to control versus what may be allowed to be under her control. If she feels too controlled she may rebel more and/or avoid taking on responsibility for herself and the baby.
Remember that you can't change her, you can only work on setting appropriate limits and consequences given that she is living in your house. It is also time to begin to see her more as an adult and avoid enabling her whenever possible. Since you can't change your her, one of the things you can work on is you. Remember to take care of yourself by a focus on healthy activities such as exercise, eating healthy, hobbies, time with supportive people, etc. Above all, make sure you give your daughter and yourself unconditional love. I wish you the best with this difficult issue. Please let me know if I can help further.
