To wonder if there is the right job for me....

[Jaynenotjane]

I'm looking for some advice really, I have been teaching on and off for 15 years, have taught mainstream, sen, have done 2 seperate years supply so really have been in many different school set ups and met all sorts of people. My problem is I just cant seem to settle which makes my cv look horrible. Since my children were born I had PND and other bouts of mental health, and often times of not coping so handing my notice in rather than trying to get better. I am currently teaching maths mainstream secondary but feel like I need to follow my heart which is primary. I don't know what to do, or if I would ever get a job, I hear the expression of "if you don't try the door you don't know if it will open" and feel I should just give some applications a go. I am hard working and know deep down I am a good teacher, I feel so sad that my career hasn't been what it potentially could have been. I feel like I have wasted 15 years and wish I could restart and try again, I know I have so much experience behind me but it feels so pointless, when anyone looking at my cvs will see so many different jobs.
Anyone wise and able to offer any advice?

Why do you feel primary is the right move for you? I teach a different subject and have recently taught it at primary level in an all through school abroad. I thought I'd enjoy the primary bit but I actually dont like it one bit! Kids are lovely but it really isn't my bag and I'm looking forward to teaching secondary only again next year.
Try not to feel that the grass is always greener - I've worked in a load of different school types and theyve all had pros and cons. If you dont like your current school or its culture then move on by all means but nowhere is perfect and primary is hard!

Oh also I have has loads of jobs as for a time we moved a lot due to my DHs job. It's not once stood in my way of picking something else up. Nobody has ever asked me about why I've moved a lot and I dont worry about it - it's just the way things have worked out and I have good references. I would imagine as a Maths specialist you dont need to worry too much.
