Thanks for the support guys. I have been speaking to some of my colleagues as well (ofc I didn't tell them about the bipolar part) but they have been really supportive ☺️
Like what is the best way to raise to HR and protect myself through constructive criticism so my character is not soiled.
Reb569, yes he is technically my boss. We were good friends before this episode. As it happens he has been feeding me with what I now believe are lies about other people:
One is doing / needs counselling
One is incompetent
One is over dependent (this guy got fired

)
All of these people are decent people (I know all of them) and I almost think he was trying to keep me away from them
To be fair my view of him is rather biased but I have no doubt the rumours will persist even if I leave.
Senior management is setting a meeting between he and I (I am sh1tting myself). It will be mediated by senior management but I think ultimately this is an interim to HR.
I'm not sure I'll keep my cool during the meeting
