what shall i do?

i've been busy lately.
nothing i can put on DA yet cause tis for a book project and i don't want to spoil the fun
but i'm back on drawing and painting.
ventured a little to aquarell painting; still not my medium
the other thing i'm working on is a "just for fun/hell i'm bored" project i'll keep it updated on my scrapbook, but it's nothing wild. i just have the hardest time leaving the pencil out of my hand.

like always more painting sadly means more health issues
my back is killing me even tho i always try to keep a good posture when working.
had some mean spasms in my shoulders last night; haven't been there for a while. funny enough my right arm and hand act up; i'm lefthanded
(i guess that's still an issue from the accident last year...)

and; even worse, drawing screws up my eyes
as you might know my vision has never been good. got my first glasses when i was around four and spent a good deal of my childhood wearing eye patches and other "correctional aids" to no avail.
(well pirates weren't in fashion back then...)
leaving me with no 3d vision, sensitivity to light and with really bad night vision. *yay* for me.
a few years back my "good eye" started to go down hill too. nothing majour, just a little short sighted.
but when i draw i tend to strain my eye(s), not blinking enough, staring at the paper for hours at times, concentrating on details, and of course... brigth light and white paper....
i know, when i draw a lot reading a book in the evening is out of the question, usually even TV is out of the question cause everything is blurry. so i'm usually the one with the tea bags on her eyes and a good CD.

In a weird way probably the only thing i'm good at, really limits the scope.

Another limitation is the weather; and here "finally" we arrive at my problem....
i have a drivers licence and a car (well it's french so tisn't really a car...)and with some luck and a few tricks i got no restrictions in my licence (i'm jut not allowed to ride big motocycles)
but i prefer not do drive when it's dark, cloudy, foggy etc. cause i know my vision sucks then. (well more than usual)
if i have to drive i do only routs i know like the back of my hand and mainly within city limits where there are street lights.
On sunday night i was invited to a friends b'day party. it was dark and the fog was immense. even tho i knew the route very well i was shaking when i got out of the car.
due to the drawing strain my night vision seems worse.
Now i am invited, by same friend, to a klezmer concert.
i love klezmer, and jazz, and baroque music, and rock, for that matter.... it'll be the opening of a chagall exhibition and she'll be playing there with her trio.
they really make good music and i love listening to them. and chagall is ok too
but the exhibition / concert is about 45 mins drive from here. and i've never driven there.
Comon sense tells me i shouldn't go there. i have no idea how to reach the location by public transport and it'll be already dark when the thing starts.
there's no one i could get a ride with.
and if i'd find out the way by train and bus i'd probably need around 2-3 hours and would have to close the shop rather early
i really want to see them perform.
how to call it off?
tis rather difficult to call something off when you really want to go there.
i guess i'll write her a rather kind email...
she knows i'm not comfortable with driving at night.
but still...
they gave a little impromptu concert at her birthday and they were _really_ good.
*sigh*
poor me
