Child missed mass due to parent/ circumstances. Does anyone need to go to confession?

[Jessie]

I used to be very lukewarm in my faith. Mass was a duty and obligation (often painful) . I’ve recently really felt moved spiritually and finally found a wonderful parish and have fallen in love. That sounds weird, but it is how it is. And now I see what a sinful awful life I have led and I want to do my very best. So in the past I might have missed mass or tried and not worried too much if it didn’t work out, now it seems like a big deal to me and am really gutted and feel I’ve failed and just wanted advice. Which I have got. Thank you. It also helps, because in the summer we will be going to Japan for 3 weeks and I’m already stressing about how I’ll be able to get to Mass.
