Do I sound petty?

[ForOliveShaker]

I work in a toxic workplace. Things have shown themselves over the last few weeks that make me feel I’m losing faith in humanity. I can’t be a nasty person and I feel this place I am at could make me. I work in education.

1. Staff member in another team lost her sister. A collage who is a wannabe for the in crowd said to me “earlier (bereft colleague) was complaining 2 days wasn’t enough for her to grieve. She wanted 5. I said “we are not the ones to decide how someone grieves. Then changed the subject.
2. Told a colleague in another dept who I have been out with on numerous occasions that her nephew does not have the correct qualifications to get one to my course. Colleague proceeded to ignore me with no explanation so I did the same back. Team leader called a chat about this with all involved. Nothing got resolved and the colleague said they felt stabbed in the back.
3. I used to go out with this colleague outside of work and actually remember the countless times I’ve been stabbed in the back by them telling others my personal circumstances that required time off the once. Then telling my ceo of the trust that I was considering leaving at one point, then mentioning things to others that I said in confidence.
4. I made a serious error yesterday and I’m aware of the severity. It wasn’t life or death just not a good mistake. I’ve come off sertraline so I’m making silly mistakes. I got one email from the main receptionist. But as I was busy couldn’t check. Then another from the office lead who basically framed the email like I was incompetent and reduced me To tears which is not like me
5. another colleague always turns to me with her problems and I can’t cope I’m going through my own things and can’t handle it.
6. I feel like a pressure cooker
7. I’m struggling to be on time for literally everything and waking up for my alarm is a chore
8. yes I have a therapist.

i realise it wasn’t the right time to come off sertraline but doc has reduced dosage now so he’s told me I can’t mess around with it again for a while and just see how I go. Am I being really petty? Also, I know some people will want to annihilate me in the comments but I do actually just need some advice

I'm sure I read this earlier and it had replies. Have you posted it twice?

I'm sorry to hear that you are going through a difficult time.

Situation 1. I think you gave your colleague a good answer, about grief. And good to then change the subject.

Situation 2. Talking about a colleague's nephew - what does your colleague really know about her nephew's qualifications?

3 - 6. I don't really know what to write here.

7 Can you go to bed earlier?

8 Good that you have a therapist!

Can you look for a new job?
Is there anything good about your current job?
You write that you work in education. Do you like the teaching part of your job?
