Mum i want to convert

Anywho,i told my mum that i wanted to change my religion (from catholic to buddha). She said that it's ok to tell her things and no matter what,she's still ny mother. Well look at how that turned out. She threatened??? Me (i suppose?? Ig?? Idk if it actually considered as a threat),saying that our great grandmother does NOT like it when somebody in the family changes their religion then proceed to explain how everybody in our fanily who switched their religion suffers in the end. Then proceeded to add that my sick uncle could've healed if he turned back to Jesus. Then she told me to "Think it carefully". (No this isnt just a random decision i wanted,ive been thinking about it for more or less 3-4 years.) Also she acts like what im doing is a wrong mistake and she also said that no matter what, we will always turn back to God in the end. Well shucks. Idk anymore atp. Now she's dissapointed in herself ig (i get that ur child switching religion is a big thing but atleast be happy for me??? Or smth idk??? Just act like anything but that ig???? Honestly i wanna commit even more now,oh well)
