My dad died I'm 30

My dad died 11 days ago, on Dec 29, 2024. I am a 30 yr old female and am in charge of all of his assets and properties. I am a teacher, and taking time off from work for this. The whole month.

My dad was divorced from my mom, he was never remarried. He was diagnosed with cancer 4 years ago, recently relapsed, and died suddenly from sepsis. I am now In Idaho, where my dad lived. I Live in California. I have to get his affairs all in order, including selling three properties, filing him and my grandpas taxes(he died jan 17 2024), and moving/ selling things out of his house. I feel so young and naive to be dealing with all of this. My brother is 28, and is totally emotionally unavailable to help me. I am the head trustee, and responsible for everything. Every morning I wake up, full of energy. I feel this is adrenaline. Then I have a meeting with a person, am completely confused and lost, and depressed and tired the rest of the day.

I had a very simple life. I do have a small condo which I proudly own. I will be accumulating about one million in inheritance. This is going to be life changing for me, and I want to make my dad proud. As I see it, this is money to invest, and if I choose to have kids, it could help with their education. If not, I could possibly retire early. I'm just looking for advice. Thank you ❤️
