It has been a ong time since we last chatted like this but it has also been a long time since I have been able to be a little more present here (as it has for you) - so the stars must have aligned 
Often the opportunities we are handed come from unusual quarters - and unexpected. Your emploer must see what we do in you though - a strong, capable, intelligent women who has a hell of a lot to offer - so I am absolutely beside myself with happiness for you
My job teaching Art came in a similar way - I had done it before but if I had not mentioned it in the initial phone call I had with my present Principal then who knows where I would be now ...her plan became simple - I teach on class for 2 terms until the teacher on leave came back then move to Art and stay on class part-time. I did not know that was the plan until I started (initially just thought it was for 2 terms) so it was both a lovely surprise and one that has worked out so well.
You won't get this until later now @Sans911 but I wanted you to know how super proud of you I am. It really has been an incredibly hard road for both of us but we are still here (miraculously) and finsing our way again. Do not ever underestimate just how strong and courageous you are
Like you, there were times I did not think you would survive either but you have continued so many times to pick yourself up and do so much for yourself to move forward. There have of course been times of setback and heartache - but that is life and you have not let yourself be dragged back too far that you could not begin again. You inspire me so much with your will, your strength and your own determination ...super proud of you and super lucky to know you
