Think i should just make an appointment behind her back and when the time comes just make her drive me?
No, don’t go behind her back.
But you are now old enough to
tell her what you are thinking of doing (rather than ask permission) as long as it’s not something she would object to you doing
at all, and to negotiate with her about getting a ride - for example, asking her when is a convenient time for her to drive you, and telling her how you will help her get finished whatever she had been planning to do instead of that - for example, “Mom, you’re canning the vegetables - I’ll do the cucumber pickles when we get back, if you’ll give me a ride to Confession.”
Plus: ( kind of related) My church is a “franciscan community where all are welcome” i know it says all are welcome, but does that mean i have to become a franciscan or something before im welcome? ( i recently discovered this church and decided to start going there because the other one was like 45 minutes away and this one is closer, but i’ve never gone to mass there)
“All are welcome” includes you.
As far as being scared to make the appointment - I know exactly how you feel. I hate phoning people for anything, and I always have to write out a script ahead of time, so that I don’t forget to say what I meant to say.
What will happen is that when you phone the Church, a secretary will answer. Ask her what is the best way to arrange an appointment with one of the priests, and then follow her directions.
Usually, they will leave a message for the priest to get back to you, and when he does, just explain to him that you need to make an appointment to go to Confession, and he’ll take it from there.
If he doesn’t call back within a reasonable period of time (a day or two) then call back - sometimes they are so swamped with messages that some get lost - don’t take it personally; it’s never on purpose.
