Hi everyone :)
Thank you so much for all of your replies so far. It's so interesting how everyone who's posted on here have had varied careers, and really inspiring to read how you can start in one career or line of work and still change several times before you find the line of work that really suits you :)
This is a bit of a thread derail - and quite outing as well! 
I was just wondering if anyone has any ideas or suggestions about my particular situation please? Graduated from RG uni with Languages degree and tutored for a year before starting a teacher training course.
I started a teacher training course in summer last year, and resigned last winter. I think that a lot of how I felt was perhaps due to the management of the school that I was based in. It sounds weird to put it into words (especially considering that I wasn't at the school for very long!), but I did wonder for a while if I had something like post-traumatic stress disorder or something similar.
When I resigned, the relief of no longer working at the school was absolutely enormous, but I just couldn't bring myself to actually do anything or go anywhere for around four months or so after I resigned from the course - it was like a really deep depression.
The training scheme that I did before resigning wasn't Teach First, but was very similar and I've actually applied to the TF training scheme in the past as well. I absolutely agree 100% with the aims and ethos of TF and the place that I trained with, and think that the work that they do is fantastic. However, it can also come across as a bit culty - and it is, of course, very, very intense.
Last night, I actually wondered if it was worth reapplying to TF or the place where I originally did my training scheme (in a moment of madness!!!)
I've since realised (after quite a lot of thought) that I would really love to be involved in the policy side of education rather than the school side (being involved in making decisions and initiatives that have a positive impact on children rather than being on the 'frontline' and delivering these initiatives as a teacher, if that makes sense).
I've been looking into roles at educational charities or social enterprises connected to education (e.g. charities set up by former Teach First participants), and the organisations Year Here and City Year, which both sound really interesting.
Does anyone have any experience of either of these please, or ideas about how I might be able to get involved in the policy side of education please?
Thanks so much again!
