I think I felt the call to Religious Life when I was about 16 or 17. I didn't even really know what Religious Life was but I felt God calling me to give myself totally to Him. I had a conversion back to the Catholic Faith when I was 19 after I had been involved in an evangelical church for about 2 years. I dove into my Faith and started to go to Mass and say the Rosary daily. The Lord blessed me with many strong Catholic friends that I met at retreats and conferences.
Now that I look back I can see that God was preparing me for Religious Life.
The hardest thing for me was leaving my family because I am very close to them. But I have come to realize that the separation has actually helped me to love them more and my desire to grow closer to Jesus has also grown.
My family was a little shocked at first but they love me very much and just want to see me happy. Most of my friends were very supportive and one even said, "Yah! I'm going to have a nun for a friend!" The people I went to high school with and some of my relatives had seen me heartily practicing my Faith for the past few years so they weren't too surprised, but I could still see they didn't fully understand.
I love it here in Religious Life! And my advice to any person who thinks God might be calling them is to "come and see". You owe it to yourself and to God to check it out. God bless you and may Our Lady guide you!
