Having that appointment this morning would certainly have been difficult - especially since this is new and you have to set down some of the history @Faith-and-Hope I can especially appreciate that talking about your mum would have been heartwrenching for you - such a wonderful women and role model for you - she would be so proud of you though Hon - you have the very best parts of her and live by her example - what more could a mum ask 
The photo thing must be difficult for you both to have to deal with as well - the whole process does not allow for differences to be taken into account - definitely not an easy thing to have to get organised.
D3 is doing what she needs to do to get through right now - the pressure from Mr. would not be helping but it is good she has a couple of days grace and can hopefully sort out her part time study in that time too. She needs a little space to be able to make some decisions for herself - that is so important to her confidence and sense of self-worth and if going part time will help in all that then it is a great choice - it still keeps her studying but tackling it at a level that she is more comfortable with.
Are there still the issues of some of those coming for Easter not wanting to generally be staying in the same place? The idea of getting everyone together is a nice one but it puts added pressure on everyone to drop everything they are doing to accommodate it - that is a tough one as I am sure you would love all your kids to be together but only if it is right for everyone.
I hope you can get some sleep early tonight. You really sound like you need it Hon and we know things can seem even more unresolvable with a sleep debt hanging over you as well.
Here walking with you my angel and holding your hand all the way
