Hi.
I agree with Tomas73, that practical help and advocacy, rather than "support group" assistance is beneficial.
I live in New Zealand, where autism/AS is not, er, how to say this..... as much in the news as in the USA and Europe.
The population is much smaller, and people here tend to have a black-and-white view of "disability", in which there are either "normal people" or "disabled people" (non-verbal, wheelchair-bound etc etc).
Therefore the "disability support" available is geared toward those people.
Personally, I could do with an employment advocate, who would make initial contact with potential employers, saving me from those anxiety-inducing phonecalls. But no, I'm too high-functioning to receive assistance and I can't pay for private help. Sigh.
I know one thing that helps with my practical function, and Temple Grandin talks about it a lot... to have a clear behaviour around things like grooming, chores around the house, manners and so on. She usually talks about this in terms of teaching functionality to a child on the spectrum. However, it applies equally to adults.... just that we have to do it ourselves rather than have a parent or therapist teaching us.
For example,
I wash my hair three times a week (otherwise I would forget entirely).
Tuesday I vacuum the house.
Wednesday is rubbish day.
Thursday is cleaning the bathroom.
If job seeking, apply for one position per week.
Have dinner with brother/s once per month (otherwise would never see them).
I think it's best not to become too strict about my routine, because I want it to be productive i.e. achieving the practical goal, rather than doing it for the sake of "doing a routine". So, if I don't get around to vacuuming on Tuesday, I do it within the next day or two. Spacing out practical tasks this way stops them building up into a massive task, and helps keep my energy moving forward every day.
I'm sure there are other things like this that we can do as self-help, when there is little else available to us.
