Mind of my Stroked Brain

I have been asked by many earlier to start practicing writing with my left hand. I think the last time I tried it was a year ago. I realised writing was far, I couldn't even hold the pencil. That was the when I had stopped. I was asked again a few days back - this time by my SLP therapist. I would have ignored it again, but I was given additional logic that it will help the balance of functioning of both sides of the brain and help recovery. The skeptic in me spoke to me pointing out that there was nothing wrong with my brain (both sides) and it was far below in the brain stem. I finally thought - what is there to lose, some more entertainment during the day sometime. So I ignored the skeptic. The poor experience of the attempt last year was not completely forgotten. I decided to take baby steps before running. I ordered a "join the dots" book. It was advertised as "for ages 3-4 years". I thought - sounds right. I am 3½ years into the stroke. I got it yesterday

Its been 27 months since I've had my stroke. I'm unable to speak ( no breath support, very less vocal chord movement and can't move my tongue or lips much) . However after first 4-5 weeks of confusion, i have been able to think clearly and read and understand correctly. After i could manage to handle the phone, i have been writing (messaging, mailing) well. However, in the last couple of weeks, i have noticed something strange. When i type a message or a mail everything seems fine but when i re read before sending, some words will be wrong. No it's not typos or small spelling errors, nor is it small words like 'at' or 'is' or something similar. Whole big words 5-6 characters i would have typed completely gibbirish. Completely random letters.  In my mind, i would have thought correctly but typed something different. The number of characters will be correct. Like a 5 letter word will be typed as 5 letters of nonsense. It doesnt happen everytime or some len
