This thing was something that made me sad which turned into a nice thing.
As per usual my supervisor decided to be a b**** to me & I was upset about it.
So one of my awesome colleagues said to me "Don't react to it. It's just a reflection on who is the better person!" Then she spent the rest of the day going on & on about how I'm an asset to the team & that she understands why i want to leave (the supervisor & manager are both horrible) but that the team will be lost without me if I do leave & that she thinks anyone will snap me up straight away because I'm so good at my job. Then she offered to be one of my referees.
