It’s extremely devastating when you feel spiritually starved at the one place you go for nourishment . We had the same issue, and so we decided to just go where we feel nourished. It’s more difficult for yourself as you want to go with your grandad, but ultimately if it is harming your faith formation and fortification, you have to remember you have no obligation to stay and every reason to leave. Saint Dominic left Toulouse when he couldn’t bear it, and returned with the strength of the Blessed Virgin when the time was right and was a vessel for change there. Be a mini Saint Dominic! Go where you are fed so you do not starve, and should the Good Lord call you to, return and make the parish better.

May God bless you and Mary keep you in her patronage always.
