I know what you are going through, I have a nunber of back issues plus the Doctors had me on oxycontin for 13 years, just burned my brain out. I have been off for 6 years but the brain is slow to recall things I use to do without thinking. I gave up for a long time but now it's just one day at a time, if I have problems I come here and can usually find what I need. I am still having trouble with sewing my seams straight, so I measure after ever seam I sew. Takes a lot longer but in the end I am not so upset with the look of the blocks. Hang in there it will get better every day, as they say use it or lose it.
