I am so glad your boy is back with you again & hopefully back 'in line with you' with what is going on. I hope he will be supportive of you as you move forward with your treatment xxxx
Which Uni is your older boy going to be studying at? Is there any way you can contact the University to see if there is a 'live in' option for your older boy - this way they are still 'away from home' but under some 'on campus rules'. My niece did this at Wollongong Uni & it worked out well. She had her own room but had shared cooking & bathroom facilities. If she was accepted as a 'leader' (i.e. checking on vulnerable students to make sure they were OK ....) she virtually got almost free (or very much reduced) accommodation at the Uni. It was also very character building for her - as she had to be a very much responsible person (even tho hormones & natural instincts were being ignored!) Don't be afraid to use the BC card too ..... it may help you get preferred treatment ;)
All the best xx
