None really fit - I am a very hands-on practical person but I don't really do things based on advice or instructions. I need to see how things work and are done etc.
If I was to replace practical with pragmatic, and the top option was most pragmatic with the bottom one the least, where do you think you would fit?
Top, I should think. At least going by this definition:
"Dealing or concerned with facts or actual occurrences; practical."
I'm crap at thinking about stuff and trying to figure it out in my head because I need to see them in front of me and need to do stuff with my own hands to understand it.
PS: But again, only the top option if you ignore the advice part.
I am highly independent and hands-on and have learned to deal with my communicative disability by doing everything for or by myself (including finding information etc.), apart from rare occasions where I have to rely on my partner or a parent to interact with others for me. That is, in cases where communicating to someone close to me what I need them to do, is easier than trying to communciate what I want/need to a third party.
In that respect I am every bit my father's daughter
PPS: Erm, that is not to say I always succeed, or that what I do is done "the right way" (or even works). And it does bother me when things aren't done right or neatly, but communicating my needs is usually a much bigger hurdle than doing it myself or putting up with the results of my endless careless mistakes.
I've cast my vote for being Impractical. I'm a pack rat. I even keep clothes that I've worn out. To take them with me when I go out to the waste areas where I hunt for corks. I'll light up a cozy little fire and burn things that I don't want to keep, mostly old clothes.
That sounds exceedingly practical to me, TBH.
I have a lot of trouble doing many things for myself, especially communicating to people I don't know
That isn't doing something for yourself though, that is communicating your needs. Doing it for yourself would mean going out there and doing whatever you're asking that person to do for you.
I find it strange, as I don't know anyone like this (besides me.) I am so highly inconsistent, it becomes eerie.
Your self-image seems to hugely differ from how others see you, so it may be possible that you do actually know people like that. You just cant tell just by looking, just like others can't tell by looking at you.
I also meant cognitively inconsistent, in fact all through school teachers would put the comment "inconsistent" on my report card.
Classic ADD. Shame on your teachers, seeing as though you were diagnosed with ADD, no point in rubbing it in all the time!!! 
I was never diagnosed with ADD. Nobody ever even suggested it to me, not even once, until I got to 10th grade in high school.
I thought you said you were diagnosed with ADHD? AFAIK nowadays people call it ADD instead of AD/HD.
That's partly ADD, but I'm talking about natural cognitive skills being inconsistent in strange ways. For instance high verbosity, large vocabulary, excellent descriptive writing, but very poor reading comprehension, poor abstract thinking skills.
Oh I see, you mean an uneven skills profile, sorry I thought you meant inconsistency as in one day you can do something, the next you can't.
PS: As for the uneven skills profile, I said it before: Without an actual IQ test that measures this you can't say whether or not you do have this.
I've been collecting screw corks for 6-7 years and I've been broadening the categories of related objects to other things. As long as they're of plastic material; have interesting colors; are parts of things; I've even started to take care of colorful schampo-containers. It haven't cost me a cent; because these things are everywhere. I think you should start collecting something. It's FUN.
Do you mean screw caps? Corks seem pretty but not plastic unles sthey are new wine bottles. Corks are made from cork, normallt.
For me, it's drawers I love. Any TV show that has filing cabinets and tiny intricate drawers in the background gets me excited (Dresden Files, Life on Mars etc.).

PPS: Executive dysfunction (integral part of ADD, and often part of Autism, AS, Schizophrenia, Depression etc.) kind of seems to fit what you described pretty well anyway.
Well you sure said or rather wrote that you had been diagnosed, but whatever floats your boat. You sure are inconsistent, especially as far as facts are concerned.
I apologize for not making that clear. I should have said my childhood ADD is a self-diagnosis.
That doesn't really sound like what you wrote before, and why would they have medicated you for ADD (albeit unsuccessfully) if you had no diagnosis?

That doesn't really sound like what you wrote before, particularly since you were constantly trying to convince people you didn't have ADD but that everything that people said was typical ADD was due to AS instead.
