Denae,
There are many things going on here. First your mother has a predetermined idea of what she wants for you, but maybe really just herself. She strongly hopes that you will seek a life that she wants. She may have issues that she has never talked to you about. Second, there are some circumstances that may require you to take care of your parents, similar to a vocation. But that’s not clear here. Apparently you’ve been spending at least a year or two thinking about this. If you feel a burning desire to devote your entire life to Christ, the peace will never subside unless you answer the calling. You should follow where God leads you. The religious life is not for the weak at heart so make sure you seek this out carefully. Set some time aside for a serious length of time in retreat to contemplate Gods will in your life and dedicate several hours per day praying, meditating and listening. I recommend Eucharistic adoration. This will definitely help you find your way and stand on your own when you’re ready.
If life spins you around and you end up getting married, as I did, don’t get discouraged all together. The married life is a vocation. There are other vocations that would allow you devote your life at being a very good daughter to your parents, dedicate excellence at your work, be the best mother, i.e., being the best you can at the ordinary life with the everyday mundane things. Opus Dei is one organization dedicated for such persons. Don’t believe that non-sense on the Da Vinci Code. That’s just a lie made up to sell books and movie tickets. Opus Dei is a wonderful way of following a vocation. They have a website. Google it. There are also 3rd order secular married groups (Franciscans, Benedictine, Carmelite) on this board that you can devote your life too. But those are organizations that require being married to the right person to make it work. These are alternatives that you may find helpful.
But in the end, you have to make the decision in spite of your parent’s wishes. Seek a spiritual director with your thoughts. I began seeking my vocation as a senior in high school. I just found out that I scored very high on a vocation inventory that says I scored higher than most for the priesthood. Well, I’m married with 3 children and I think the test is for any vocation. So I am looking into the diaconate at the age of 45. So you still have time. Don’t rush anything. God brings you, you need to listen. But don’t waste you life on silly stuff that just puts it off. Do some research on your own. You have to know this is what you really desire. Life experience can make for a better vocation so don’t think that you have to do it right away unless you’re that determined. Most, if not all, orders provide a trial periods that allow you time to see if it’s a good fit for you and them. Begin your journey by looking up the vocations director in your parish. Don’t let family get in to way. However don’t forsake the needs of your parents. Grandchildren do not qualify as a must. The scriptures say the children are a blessing, not a possession.
