user19313: I'm a 16 year old girl and at a time in my life,I have been used to watch inappropriate things.
When my parents found this out,my mom got me promised to her in front of Buddha to not to do it, and I promised her with pure intention of keeping it.
Then by the time, when I just turned out to be a teenager I just got and urge and curiosity to see them and I watched them again.
Is this even a promise, if it is a promise according to Buddhism then have I done a sin?

user13709: MN8 has many sayings that apply. For example, you understand your action as breaking a promise:

MN8:12.15: ‘Others will have wrong action, but here we will have right action.’

And if your promise was insincere, then this would apply:

MN8:12.6: ‘Others will lie, but here we will not lie.’

There is another issue here however. I remember being very skeptical of authority at 16. I needed to understand directly the what and why of everything. Perhaps  you might feel the same. The nun Dhammadinnā expressed this as:

MN44:24.4: Neutral feeling is pleasant when there is knowledge, and painful when there is ignorance.”

While you wait to grow to the age of making your own choices and way in life, you can take a good look inside to understand the nature of your impulse and let it go.  The world today pounds us incessantly with things it wants us to want. Yet if we identify with those things that change endlessly, we will become unhappy and suffer. We will become hungry insatiable ghosts.
Your mom has seen more suffering and ugliness than you have. These things are difficult to talk about and very very real. Your mom understand this truth:

AN4.9:3.2: that craving is the cause of suffering—

She understands this truth and, loving you, does not want you to suffer. And perhaps if you approach her with an apology, she might be able to explain how she feels. Be gentle, however, because such things are very difficult to talk about.

user19314: First of all, and for the case it's a promise to abstain of bad thing (as breaking of a promise to abstain from bad coming with it, wouldn't be kammical a bad thing): Sadhu for openness and considering a fault, wishing to do things right, of which is actually very praiseworthy, making you a serious conducting person for many good people and a good example of acting for many others, that things can be solved by confessing and strong determination not to do it again.
The teachings to Rahula, the Sublime Buddhas will be good encouragement, starting about lying and guide for all days actions.
Yes. Twofold, no threefold, no fourfold grave, good householder's daughter. One is the cheating, breaking promise toward your mother, a child's first God. Second, it was a promise to do what is good, a 'holy' promise, for your own support, breaking which turns foremost against yourself, maybe not seeing the disadvantages of what the householder's daughter went for. Third, hurting oneself, causing long bad periods of consciousness, in violating a fundamental precept. And fourth, at least, 'cheating' the Buddha, of which can fast turn one away from the Jewels, requiring renewing refuge to walk on a good way.
So, but all of that can be solved by best confessing as fast as possible (both, your mother, not to speak of the Buddha, will highly praise your deed if doing so, and accept it), renewing the promise, best taking five precepts seriously, and keep a strong determination to follow it steady in mind. Confession itself has actually already been made by the question, and surely that gave already good release -- but also good, for good relation, to ask for pardon from your mother, and best doing it as well toward the Buddha, and the Jewels, a little cleaning ceremony, which brings sure a lot of joy and good self-estimation.
As for reduce the danger to do it again, best cut of ways of access to it -- including bad friends -- and inform yourself about the disadvantages of it: best if approaching wise people in detail of it.
It's totally the way the Buddha's path to liberation, peace, works: by confessing and steady better new begin, cleaning is it called, or lifting oneself out of a hole one has fallen into, by doing so.
Best wishes and never be shy in doing what is good. Mudita

user10844: Talia, there is no 'sin' in breaking a promise made with pure intentions of keeping it. (In fact, if someone promises with all his heart to kill me, I hope he breaks it!)
Even for monastics, like me, we occasionally have to break our promise or agreement to do something (such as accepting a invitation to a meal or to give a talk) when something else more important crops up. It would be unwise to think we have to keep all our promises, made based on circumstances at that time.
It's only wrong if we 'promise' with the intention of not keeping it. In this case, the so-called promise is actually a deliberate lie.
Can you actually be sure that you wouldn't do something in the future? I can't. I know my mind now, but I can't know how it will be in the future. So, how can we promise what we cannot be sure of?
