Took mine (my eyes) 6 weeks in total from the day I was diagnosed and had my first insulin jab to get back to near normal which meant I could get back to work, since I was a clerk so I needed em in full working order to read and write - of which I was mighty glad cos I was bored out of my brain by then - no way had I been able to read, knit, sew or even concentrate on TV for very long although that wouldn't have helped as there was nowt on TV during the day in 1972 and no kids so not even that to take up my time, and no money and frightened to walk the 2 miles into town to the shops on my own 'in case' as adults weren't told about the usefulness of a couple of jelly babies back then since with the insulins available your choices were limited really to 'proper' food.
Try and keep stuff as simple as you can for now - once you're used to dealing with the ordinary things, then start gradually getting more adventurous. If you do that - take it slow enough - impossible though it seems all this new and different stuff will just become 'normal' for you - honest !
Ask ask ask ask - we - and your hospital clinic DSNs and consultant - would rather be asked 10 times and explain it again, until you're confident you understand it.
