It's really stressful, but I want to know what my dad is doing every minute.
Why is it stressful that you want to know what your dad is doing every minute.
I don't trust him, I think he's plotting against me.
If your dad is not telling you what he is doing at all times, you need to respect that. Someone does not have to tell you about themselves all the time.
I can't allow him to plot against me, I need to know what he's doing.
It sounds like you really have some issues with your dad. I think you should talk to someone about your trust and stress issues. They can help you work through your problems.
