@tarazkp I understand when you say that writing is a kind of catharsis, it's the same for me, it helps me to let off steam and also to clarify my thoughts.
Regarding your therapy, your state of mind influences a lot for the exercises, you should always try to be relaxed and with a good attitude to do it, I had facial paralysis and that's why I tell you that as far as possible you should avoid stress, being tense does not help.
Writing is probably the most valuable pastime I have ever taken up.
