Okay I wanted to watch it again before answering this, and as I have watched it all again now, sadly, yeah.. It is over, the last episode makes it clear… But anyway, the show had a great potential and it would be amazing to have a 3rd season, but it probably won’t happen ahah. And as it is based on an actual diary that someone wrote when they were a teenager, I doubt they’ll write more, it wouldn’t make sense if they started to come up with stuff that didn’t happen. So yeah..
Although nobody knows the future of mmfd. E4 have said they are interested in renewing if the whole dream team where to return.
But as for the Diary, Rae Earl has said in an interview although she only published two diaries she has more writings and stories she would be willing to tell and provide for the TV show
Not to mention, the show is BASED on diaries, not an accurate timeline of Rae’s life. Liberties were taken with both series, but especially with Series 2. Rae Earl said she didn’t do many of the things in that series, but that she would have, given the opportunity.
British shows tend to wrap many loose ends up at the end of a series because they aren’t sure of a follow-up. While we may not get another series, it’s not true that there is no more story to tell about this character and her struggles.
