Are there busing options for either child? Would either be doing after school at school activities that could ease your commute schedule.
I have heard about some kids using an ADHD coach in middle school to help plan assignments and keep track of due dates. We may be headed in that direction in the near future. With a PG/2E kid, the 26% in the gifted program numbers don't appeal to me.
I recently gave up a hospital job with similar hours be make dd8's after school schedule more consistent. I miss having a job and the long school commutes aren't much fun... We compromised on her riding the very long school ride home half of the time. I hope you find something that works.
