Hello Shakin, a difficult thread for you to start but my heart goes out to not only you but your daughter as well as your Father, an unbelievable amount of pressure instilled upon you, now and in the future.
As you have an excellent doctor is the support you need as there will be many questions you will want to ask on a continual basis, and unfortunately, that's to be expected.
Can I please suggest that ask the doctor about the 'mental health plan', this entitles you to 10 Medicare paid sessions with either a psychologist or a psychiatrist, someone who is warm and gentle but experienced, because you need to be strong and when this happens, it will be better for you to show compassion, and please I don't mean anything to upset you by saying that.
Your daughter is able to contact Kids Helpline 1800 55 1800 by phone or online because she maybe changing, and I can say this because of my own head injury.
Would love to hear back from you.
