Perhaps after a year of individual therapy you will cope with group therapy better? IT is frustrating not to continue with one person in NHS but quite often it is time limited - often 6 or 12 weeks only where I live.
Group therapy may not be ideal, but better than nothing and perhaps at a different time in your life it would have more benefit to you as you now understand your issues better and therefore can explain yourself more coherently.
Are you able to consider private therapy or a charity like willsurvivethis suggested?
