Gardenmama, thanks for your message. A burden shared is a burden halved. I think at that age most normal young people are self-centered anyway (I don't recall much consideration for my parents feelings either). Our kids with their challenge are even more so. I think the onus is on us to remain healthy so we give our kids a hand when they are done and are ready to move on.
We had a fun day at little beach town today with some friends. I have also Scheduled an appointment with psychotherapist next week for talk therapy to manage stress related to my son and work. Once I get busy with work next week I will not likely be thinking about my son too much. The stress of work will likely displace it.
