Relax, it's a normal thing, it happens all the time.
You were raised in a paticular culture and an assumed religious faith.
No one probably ever asked you whether you accepted that religion, you were just fed it from birth with your mother's milk (as it were).
Then at some point you went out into the world on your own. You made your own judgements including one on what you felt was your religion.
But you still had that cultural "baggage" you were given from birth. Later on, you began to doubt about your choice and when you began to doubt, you came back to your old pre-conditioning...your cultural baggage...womdering if that was the "real" answer.
The only answer, if there is an answer, is in your own heart and mimd. Only YOU can know what you think is best for you.
For that reason, you will have to make the choice of what you want as your religion or beliefs YOURSELF.
I was raised as a (Protestant) United Church of Christ follower...the pastor of my church lived in house not far from the Church I attended every Sunday as a child. My family just assumed that was what I would "be".
When I decided to go my own way, ending up as a Buddhist, they were dumbfounded...they just couldn't believe it.
Their doubts about my choice were passed on to me...are you SURE, they asked me?
Because they questioned my choice I began to doubt my own choice. In my enviroment Buddhisim was "wierd"...why couldn't I just be a "normal" Protestant Christian...like "everybody" in that town did.
It took me years to shed that "cultural bagggage" that I had grown up with from my childhood.
All I can tell you is to make YOUR decision based on what YOU feel is right in your heart and mind.
It isn't easy, but you have no other real choice. You must do what you yourself feel is right for you.
