Everyone is different, so this new role might be perfect for you but my experience is in line with Bitter2014. I was off work unwell for four years and went back to work full time with no adjustment period. I got promoted and moved to a better job and got promoted some more until i was in a very interesting, challenging and stressful position. It took less than one year before I was on sick leave then finally let go as i could not work. All together I worked full time for three years. Then I was off work very unwell for 5 years until I started up a cruisy casual job a year ago which I have been able to maintain well, although I have had time off work for treatment as I am still in the process of stabilising. In the end it is up to you as you know yourself best. I wish you all the best.
