Bro, you are not alone. I have similar problems with my master's thesis.
Two things help me:
- every Sunday I report to my sister on my progress - on the evening she asks me how my paper is going and I honestly answer her even if there is no progress
- I try to work on it every weekend. I stopped fooling myself that working on it on working day evenings is even possible with a kid running around.
And... There is some progress!
