The time has come

To resign from my job.
After 6 yrs as a TA with Soecial needs primary children and looking after Christopher, I have finally realised it is time for me to walk away.
This has been the hardest decision I have ever had to make, I have been involved with the school since Christopher was 2yrs old, I have spent the last 6 yrs giving back some of what was given to Christopher whilst he was there.
It can be and mostly is a very rewarding job and I have been privalaged to witness the children achieve some wonderful things over the years.
This year however has been extremely difficult, working with two members of staff that don't get on along side a very difficult class, having been bitten spat at and told to F off on a regular basis takes its toll. The class lists for next year have been issued and I am going into an even more difficult class but for different reasons and more staff disharmony.
I am both physically and emotionally drained and I can't go through another tough year.
I have been considering leaving since Dec but my heart keeps telling me no whilst my head is saying you have to for your own sanity, I spoke with my Deputy Head yesterday and told him how I felt and he said he would speak to the Head, I thought I would feel better once I got it off my chest but today was no different so the decision is made.
I wrote a draft letter tonight through tears of sadness but I know I have made the right decision, not just for me but for Chris and Rach too as they always bare the brunt of my frustration and lack of patience when I come home at the end of the day.
