Mantra: 3 more months. 3 more months.
Big ole hugs... this has been a hard year for you and your SS and family.
So... in line with the mantra... instead of trying to change everything right now (when by the time stuff is in place and working 1/2way smooth, the durn 3 months will be OVER)... why not use this time to plan ahead?
Come fall is he going to a CC? Eastern? Wazoo? UW? Trade school? Military? Apprenticing? Taking a "gap year" to work a joby-job? Going into any form of long-term employment? If he's leaving come fall, then really it's 6 months, and then *poof*, but if he's staying... then right after graduation it seems to me like the best time to start getting things set up for how you want your lives to look. AKA where he is in your lives.
I don't know... it just seems like wasted energy & frustration to try and change everything all in 90 days to have it turn around and have to change everything again as soon as he graduates. For ME... seems like a KILLER opportunity for a planning period, though.
