Yes, the emotions are normal. The wanting to follow your emotions is normal. Remember feeling do and will change.
The process of grief is leading to emotional acceptance. Along that path you are sometimes along for the ride, other times lost and can’t find the trail, and yet other times sure footed and with solid headings. It is perfectly normal to find yourself bouncing from passenger, to driver, to at times even bystander. Don’t worry you will get there and be firmly the driver seat. It takes time. Day by day, and hour by hour when needed. For a while I was minute by minute for some of those early days.
I’m glad you can and are talking to your Dad. His life experience and wisdom is pretty invaluable I’m sure.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
