I worked really hard to get my PGCE (single parent) & I had always wanted to be a teacher.
After the classic '5 years' in the profession I decided to leave because I was fed up of the lack of management support, lack of respect and generally feeling anxious ALL the time.
Since leaving I feel so much better. I now wake every day feeling good, I'm spending more time with my children and I feel positive about the future again. It's so liberating.
The pay-off is I've taken a huge pay cut... but nothing beats the feeling of calm I have now.
To anyone considering leaving teaching: do it! You won't realise how bad it made you feel until you're not doing it anymore.
