For starters, laplaceelvis, you need to quit trying to change your parents. That is not only not your job, but also the issue you bring up - their response, is generated by your insistence on bringing up the subject.
You may well have a vocation. Or you may not, but the matter of testing that vocation by “look and see” with some orders is not going to occur until you are 18 and out of the house, and perhaps not for another ten years after that.
If you are capable of college - and I presume you are - then both common sense and a respect for God’s Providence would indicate you should get into a college. Don’t expect that any order of sisters, or order of nuns, is going to pay for your college education; the likelihood is somewhere between nil and none. Most orders are not well off enough to send you to college to earn a degree from which they might benefit.
I do not say this in a negative way; just as an observation; many try out a vocation to the religious life, and some are called and some are not. Whatever you do, you need to be wise about; meaning, if you do go to college, you may want to get a degree in something you can use should you try out the religious life and find it is not your calling. that is not doubting a calling; it is wisdom. That order which you might join might need the skills you learn in college - whether that is a two year or a four year degree.
Understand also that whatever you do about college, you will need to pay for it (or your parents, etc.) as it is likely that an order will not be interested in you joining and bringing in college debt. Most have enough of a struggle to pay operating expenses and care for their elderly. Thus, you might get a degree and have to spend several years paying off college debt; remember this when you start to investigate colleges.
I thought in the 8th grade I had a vocation and wanted to enter seminary. My pastor told my parents I would enter high school seminary over his dead body (and given the amount of sexual abuse cases, perhaps he was extremely wise). I entered seminary college, spent two years, and it was clear to me that was not what I was called to do.
Currently you live in your parents’ house, under their rule. Understand that in entering an order, you will be living under the rule of the superior of the order, and perhaps under the rule first of a novice master, and later under the rule of someone else for a period of time. Learning how to live in peace under another’s supervision and rule is part of the lessons you are now faced with in your family.
I would suggest that you not only attend Mass as often as may be available to you through the week, but also pray; the rosary if not the Liturgy of the Hours (which you may be praying in the future, depending on the order you choose); and that you learn to stop talking about something that only ends up aggravating you - that is, stop trying to change your parents. Your continued bringing up the subject is stirring the pot - put down the spoon. That does not at all mean not pursuing the possibility of a vocation; it means stop trying to change your parents. That is the best advice I could give.
