Hi AvocadoAva1,
I'm so sorry about what you're going through. It sounds like you are really suffering at the moment. My mum passed away last year and I went through every emotion just at her funeral alone. Grieving is difficult and everyone copes differently. Misbehaving or being irritable can definitely be a sign of your grieving.
Have you spoken to anyone other than your mum about your dad's passing at how it's affecting you? Any friends? It might be worth having a chat to a GP or psychologist. There is also griefline which is a support service for anyone experiencing grief. https://griefline.org.au/
For me, I coped by burying my emotions and trying not to think of my mum. It helped temporarily but I had to face my sadness at some point. I also dream about her a lot. You're not alone. Use this forum as a place to vent or get things off your chest. We're here for you.
Bob
