Just wanted to share some positive news that I passed my viva voce and will start doing the corrections soon. Still can't quite believe it. It has been 4 years of (at times) absolute hell! Not just with the PhD but my personal life as well. This forum has been a constant source of support throughout that time, even for just reading through old posts and getting some comfort that other people have successfully managed to get through similar difficult situations. So, a big thanks to all who have helped me on here over the years :)
