It seems like not long ago at all you were really not doing too well at all, mentally. There seems to have been a big change in you, i wondered what the catalyst for this was?
Was there something your current T did that helped with that?

If you don't know how long the other T will be off sick for, could you maybe find another T with similar training. Because as much as you love current T, you've never been satisfied with her way of working and have always voiced concern about her lax boundaries. Maybe it's time to move on?
