Is all of this normal after the death of a family member?

My great grandma and dad both died this year and only months apart. I am unsure if the way I am feeling is normal. Before the deaths, I was happy and carefree. After the deaths, I feel like I am losing my mind. I obsess over everything. I am angry at everybody. I get irritated easily. I feel like I am breaking down. Is all of this normal after the death of a loved one? Bonus question: If it is, when will I get back to how I was before?
