NTA but I also do 5 day fasts like the other anon said, for me the first and second day are always the hardest and day 3+ onwards are a joke.
As for how I keep going? I can only speak for myself but:

>do light exercise (the 10k steps per day meme is unironically a good idea)
>keep your mind busy with work, learning a new language, a hobby, vidya etc
>drink salt water
>eat to just under maintenance on refeed day and take a multivitamin

That's what works for me.
