I'd been wondering how you were @Hazard357 . On one hand I'm glad to hear that things haven't gotten as bad again as when you posted the other week, but on the other hand I'm empathetic and sorry that things are still really overwhelming for you and distressing thoughts.
For myself I feel like distractions just delay the root issue until I'm able to seek support to process it since a safer environment (if needed) or when calmer (if due to a trigger). Never been a longterm solution for me to just keep distracting myself. Its survival, but not thrival. (I may have just made up a new word, but it sounded better than "thriving".)
New job plus double grieving. Thats a heavy load indeed. A lot of big life stress factors.
The pressure to not 'let the cracks show' in a new job can feel huge. I hope the coworkers are good caring people and perhaps can be safe to let know if you are not feeling great? (E.g. No, I'm not feeling great today. I am missing my family member who passed away. However, I will be OK and still able to work. Thank you for your concern.) It can take time to build that trust though, absolutely.
Does your boss know at all about either your uncle or mother's passing and your current grieving process?
Have you found anything yet that helps you process the grief?
E.g. honouring their memory, sharing your favourite memories of them with others, writing, etc? (Sorry, im not as well experienced in the grieving process. I have had 1 friend pass, but we knew he was ill for 12 months with a prognosis of non-recovery, so it was something I could prepare for to say my goodbye before they passed). (My uncle passed in 2020, but I was not very close to him. It was sad, and he was overseas so we could not attend the funeral. It felt surreal because of just watching via video. It was a sudden and unexpected passing).
