I tend to disagree with the perception that diagnosis = medication. I do not medicate my daughter, she doesn't need medication right now. If we all decide that her needs are best served by school at some point, we may decide the situation calls for it, though the problems I had with Ritalin make me very cautious about the stimulant class meds (severe appetite loss, which caused me to have extremely disordered eating, anxiety, insomnia, explosion of mild, subclinical OCD tendencies into fullblown OCD). For her, there is no quality of life issue that leads me to think they are indicated. Her best friends happen to be another two girls with ADHD and a boy with Asperger's, so there's a whole lot of understanding in her circles. Right now, we unschool. I hope that when she's old enough, she will enroll in a particular charter high school in our area that offers independent study combined with vocational apprenticeships, because I think that that path will serve her better than traditional schooling.
I certainly wouldn't judge someone who makes another choice, I don't think anyone who would frequent this forum would make the decision to medicate lightly, or without carefully weighing the risks.
For me, a "label" of ADHD is preferable to the labels that I might have worn 50 years ago: lazy, airheaded, flighty, disobedient, willful, stupid, unmotivated, absentminded, and weak-willed. I love having access to the experiences of people who face the same challenges I do.
Cyclamen, I find what you are saying about service/labor jobs really interesting, because it is very similar to my experience. Jobs I've had in the restaurant and customer service industries were much easier and more satisfying to me than the last outside-the-home job I had, which managing an office that scheduled life insurance physicals. I do SO much better at things that have a solid, achievable goal.
