Yes email them and send your tangible photos as well as a letter if you must. Let them see that you are human and your mental health has been taking a hit because of this process. I wish you all the best and keep strong. I know it is not easy. I’ve emailed cic-ottawa-immigration@cic.gc.ca and cpc-ctd-ottawa@cic.gc.ca. However, final email came from ircc.donotreply-nepasrepondre.ircc@prson-srpel.apps.cic.gc.ca. I have also mailed them my documents via Canada post to my visa office.
