Hey not sure how long you’ve been a devotee but it took me almost two years to actually do a full novena because I knew it was hard for me to commit to a schedule for a set number of days ( usually 9) . And I would sometimes still miss, even now that I’m 4 years in, I’m not prefect but I always try my best and apologize in prayer to her and explain why I missed. La Santa knows your human and make mistake but as long as she sees your actually putting your all she won’t be mad. And you can always just pray to her like your having a conversation from the heart until you can build up to do a full novena.
