Anyone with severe anxiety/panic disorders? - Mass

Im pretty much homebound due to my panic disorder. I go months without going outside (i dont notice it so used to it). But - doing big things as God told me to go to the catholic church so I am going. and I can feel my skin peeling like an onion with fear!

I'm Starting RCIA Mid class in four days (they started in september), only spoken to the priest once in the office, never set foot into an actual catholic church. gotta walk to and from around 45 mins each way, and I have not one single clue what mass is like or what I'm supposed to do. Seeing the priest was the first time i've spoken to a human in person outside of my husband in almost a year.

I made it a commitment that once class starts- I will be attending mass weekly. I am more fearful that others don't have this issue and I just wanted to know someone is out there struggling to go to first mass or struggled. I cant even check my mail now im going to a catholic mass LOL
