Structure to my day help needed

I don't really have any structure to my days at the moment

The only structure is I wake up at 8 am and then start my bedtime routine at 7.30 pm

I do walk the dog at 11.30 am ish 

Apart from that I don't have structure. I would like more of a structure for each day but I'm unsure how to start, plus I need to be flexible incase parents want to go out with me

I don't know where to start or just put structure in place

Any advice help etc needed and what I could do as well to structure my day
