I think she's posted a lot and she's been rejected 2/3 times for Primary PGCE now - am I right?
If you really want to be a teacher (not just a primary teacher mind) have a go at secondary - I mean, with a degree with a maths component and the desire to teach surely becoming a maths teacher would be a good decision...
Aside from this do you have other interests?
Perhaps your psychological studies modules could help in getting on a masters course for further psychological study and you could become a school counsellor or mediator or something similar...I know nothing about that side of things but maybe you could consider it?
