Dyscalculia - The MATH disability

I have hated having to do math since grammer school. I do the minimum amount, such as managing my finances, keeping logs and checkbooks in order, measuring quantities properly. But it is not ever going to be my shining talent.
Right and left sometimes temporarely befuddle me. Like when I'm working on an engine and I have to screw the bolts in a certain way, I have to do righty tighty, lefty loosy and actually make the motion of right or left with my hand. Working with propane fittings is especially daunting because the threads are reversed.
I am a clutzy dancer. I am agile in climbing trees and hiking steep trails, but I'd rather walk on hot coals than dance. Ballroom dancing...yeeg!
Fortunately I have many other strong points. So math is just one of those annoying but necessary tasks I have to do to keep things in order.
I feel for all the kids in school who are being made to feel bad about themselves because they are a little slow in the math department. The anxiety provoked by poor teaching skills and over crowded class rooms has a great deal to do with this problem.

I'm beginning to think I have this to some extent.

I've been studying to re-take the GREs after 5 years (going for a PhD... hopefully...) and have come to realise that, altho 5 years ago I always did BETTER at math, I now do amazingly in verbal skills (except reading comprehension) and am abysmal at math, especially worded problems.

Looking at that list, I remember a few things. Most people I know despise geometry and prefer algebra. I did horrible in the latter and was great at geometry (except in the advanced stages). I always assumed this was due to my memory (short and long) being visual based. I have also completely forgotten half of all the math formulas I've learned. Except geometry, which is the only 'logic' I ever really understood.

I am consistently absent-minded and I have no sense of direction, and get panic attacks when I'm lost, which led me to get my beloved TomTom. (Also, praise Google maps!)

This one phrase stood out to me: "may be able to do an assignment one day, and forget how to do it the next." I have had this issue since college. Sometimes I feel like my brain is working like a perfectly aligned clock gear, and then sometimes it feels like it's jammed. On those days, it feels like my brain literally hits a wall, and I can't for the life of me figure a math problem, or perhaps advanced science. When I was doing a research project about 6 years ago I felt like I hit this wall all the time, mainly when trying to understand my own data that I made charts out of. Sometimes I feel it when trying to contemplate heavy metaphysical/philosophical topics. Then the next day I could have some epiphany or similar deep insight.

However, I played viola for 11 years and timpani for 4, so motor skills and 'muscle memory' is definitely NOT an issue with me. I've become convinced motor/muscle memory is linked to visual acuity and spacial awareness. Math instead is more related to phonetics and musical rhythm, not so much the motion of fingers or dance steps. But that's just my observation, and I'm far from trained in the area
