get excommunicated from the Catholic church

....And she never really cared about religion until my dad died. I remember being Baptised and having my Communion and Confessions etc all done in one year. I understand why my mum turned to the religion she grew up with to handle Dad’s death. But now that I am an adult and have formed my own views I think that it is important for me to seperate myself from the Catholic Church. I don’t hate the church, or religion in general, I just don’t see how I was ever ‘in’ it. I have written two letters to the church I was baptised in but I haven’t gotten a reply. It’s hard to communicate with them because so much time has passed I can’t particularly remember the details, but I am determined to get some little letter saying that I have been officially struck from the records.
