"If someone is pressured to promise something, does it still qualify as a promise?"
Ledgewood in my eyes if you are pressured to make a promise, theres your loop hole. Sometimes we make promises because we were young when we made the promise.
If you have made a promise so long ago, and now need to break it to recieve help then its ok to break it.
A promise under presure is never a good thing,

When my Dad was passing I promised I would take care of every one. meaning my mom and sister, I did with my mom. Now with my sister do i keep that promise till I am destroyed? no .........I have done my best now its time for me to let that one go...
Under pressure promises they are only good to pressure you, just my thoughts
