It is true, I also experience this.
And also only doing things that I HAVE to do. If I have 3 days left to do it, and it will take me 2 hours, I will wait until the bitter end.
It can take me 8 hours to do 1 hours work, and 1 hour to do 8 hours work, depending on the deadline/urgency.
I find it difficult to focus on my own needs.
I also find it difficult to accept that ADHD is a medical condition. I keep feeling that I am like this because I am lazy. And this creates a downward spiral of self sabotage.
Anyway, best i try do some work,
