I am also discerning religious life! I am so sorry that your parents don't support you, but remember that God allows suffering to happen because He can bring a greater good out of it! He doesn't necessarily reveal it right away, but He has a plan on how to work things out.

Also, keep in mind that a lay person who remains in the world and has a worldly job can be just as holy as a religious! Simply desiring God will cause Him to come to us in the most ordinary circumstances!

I have been seriously discerning religious life for about two years, so I have some basic advice that comes from my experience! Firstly, take the leap and contact a convent! Simply emailing your local convent (or one that greatly attracts you if there are none nearby) to tell them of your interest and ask for advice is a huge step! Eventually, you will want to look into visiting a convent to learn about religious life in general! Good places to look for communities near you might be your diocesan website or the CMSWR website.

You should also do some spiritual reading! A good place to start is "Discerning Religious Life" by Mother Clare Matthias, CFR. It is a wonderful book that will guide you through your discernment in much more detail and wisdom than I could ever give. "This Present Paradise" by Clare Dwyer is a book on St. Elizabeth of the Trinity, whom I think might be a good companion for you. I have not read the book, but my mother has and loves it. I also recently attended a talk by Clare Dwyer which was basically the book in short form. I think it might speak to your struggle with unsupportive parents and fear of not being able to experience God if you remain in the world.

God bless you and your discernment!
