Lil......I had to do the same exact thing to Sonic.
"Sonic, five minutes to go to school! Sonic, two minutes to go to school!" Then there was still no guarantee he would not cry and be difficult when carried out to the car. The train thing is a HUGE red flag for Aspergers. MANY Aspies love trains or train schedules. I have no idea why.
Really early on, we knew Sonic was different because he came out of foster care and had been evaluated closely so we made sure he got all the interventions and that school was a friendly, warm place for him. Many Aspies are on the fringe and never diagnosed so they struggle through life. I am starting to feel teary-eyed for your son, like maybe this is him, at least a little. Maybe he really CAN'T get to work on time or schedule his time on his own...ya know?
My son never had any big strengths either other than he was a very hard worker and liked to help people...he was a very nice person. Honestly, Lil, if he had not been treated from young on he may have also turned to drugs to feel some sort of connection to people. Lots do. Why? Well, as my daughter who did tons of drugs told me, "they're the ones who are nicest to the loners and nobody else accepted me." My daughter does not have Aspergers, but is shy to tears and when we put her in a new school, she sat alone for months until the "bad" kids started to include her.
Look, I don't know if your son has this struggle. But if he does, maybe if you present it to him and offer to take him for a neuropsychologist evaluation, you can find out. Maybe your instincts were right in the first place and he does need more help than your average young adult. Sonic still needs help, still calls me all the time, but he is doing well because he has community supports.
If you are interested in looking into it, I'd go to Amazon and read a few books of Autism Spectrum Disorders (ASD), not just Aspergers. There is also high functioning autism, which is not quite Aspergers and Pervasive Development Disorder Not Otherwise Specified, which was Sonics first diagnosis (and it was hard to get). I would truly hate to see your son suffer if it really is not his fault that he struggles. And I know you don't want that. He could still live out of the home if he is diagnosed. Between Sonic's Disavility pay and part-time job, which was carefully chosen for him, he has enough money to pay his own bills. I am his payee so his bills get paid. If I ever can't, somebody else will be appointed. I'm glad I don't have to explain all this to you
At any rate, there's another possibility for you. He just doesn't seem like your typical horrible kid or personality-disordered young man who ends up homeless.
Of course, any evaluation would require his cooperation. But you know that.
I would love to see a happy ending here. I think all of us have adopted you, Jabber and your son and we all want to see a happy ending. Something about your son...is not quite the same as many other difficult children here. He seems more innocent.
Lil, spectrum kids, especially on the high end, do get better with age. But they can still really struggle if they are on their own. And they struggle over stuff that has us scratching our heads, such as common sense things. With interventions, even if he is older, he can learn to fit in better...that is if he has it.
