Why am I annoyed lately?

I have been working on this for weeks now. I have not resolved anything or at least not much has been resolved. I have prayed about it daily. Discussed it over and over with my wife and still find myself rather lost in regards to why I feel this way. 

The emotion I am dealing with is, I guess, annoyance. I feel ticked off. Upset. I feel like whatever is annoying me has been beneath the surface annoying me for several years. But what is it and why does it bother me? 

It might have started with my mom passing, or my daughter acting like we don’t matter anymore. Regarding my mother. I keep coming back to how strange it is for me to see my brother go overboard on her passing. I am not sure if overboard is the right word. He seems to be fawning all over it. He is making it sound like the loss of the greatest person on earth. So the question that keeps coming up to me is so what? Why would I care if he is freaking out over her death? 

I feel he didn’t do anything for my dad when he was sick and dying, in fact, it felt as if he didn’t want to be a part of the family as long as dad was alive, so maybe it is that. It feels like betrayal, but not just at my dad’s expense, but mine as well. For the longest time I felt as if he didn’t want to have anything to do with me, well, the truth is he didn’t. I actually think he still holds a grudge or something against me. So him not wanting to spend time with me or that side of the family is heightened when he freaks out over mother’s death, especially considering how she has treated the entire family. 

I am actually finally beginning to understand my mood. Wow. Perhaps it was too complicated before. 

So my mother, cheated and left dad and immediately proceeded to live a life of sin including being a lesbian, sleeping around and smoking. She went full liberal. We tried to help her repeatedly and she refused. Not only did she refuse, but she did so with insult. 

Dad never did any of that. 

So Drew wants to ignore dad, act like he doesn’t matter, but fawm all over mom? He avoided me and my family, but when it comes to mom dying he wants to do all these things to remember her like she was a goddess or something.
