Hi guys.
So my birthday is tomorrow, and as my present, I asked my parents to let me go to mass. So my dad is taking me to TLM on Sunday of St Rita's feast day! Yay!
Congratulations! Thanks for informing us of the good news.
I've already done a full examination of conscience (wrote it down because I am forgetful).
This practice is discouraged. Maybe you should read over your notes so you don't forget, and then destroy the paper before you go to church.
But I fear that I won't receive communion worthily. How do I do this? I do not want to disrespect God. How do I prepare?
You are starting out with the right spirit, so you are far ahead of many who have been traditional Catholics for a long time.
Traditional sources say that preparation should fall into 2 categories: Remote preparation and proximate preparation.
Remote preparation is what you do beforehand. In your case, it's your whole life. On a regular basis, it would be the evening before. Remote preparation essentially consists of straightening out your life so you are worthy to receive.
Proximate preparation is right before and during Mass. Proximate preparation is focused on your heart - being in the right spirit to enjoy union with Christ.
