Sorry this is long I have no one irl that I can talk to.
I volunteer with CAB, just had a bad day. Everyone in the office was really supportive and I felt fully backed up but I feel a bit crap. Three or four really nice clients. Couple of clients that were angry we couldn't help, just a bit loud. Then the one that was shouting first just about the situation (I'm used to that) then at me. Last one I feel like a failure. I'm experienced and feel I should have been able to manage and just assertively tell him to leave. Actually escaped and got someone else (supervisor) to. Was really upset afterwards partly just shock, also wondering if could have handled things better (I couldn't). I did see a last really nice client so at least back in the saddle.
I have done assertiveness and a course on dealing with difficult people. I know it is my poor mental health rearing it's head a bit, but I feel useless and rubbish.
I'll be back in tomorrow just need a handhold now.
(It also feel very grateful to the frontline workers in things emergency services and hospitals who deal with this all the time - at least we can ban people relatively easily.)
