Are you a convert to Catholicism or are you going to a non-Catholic church.?

I want to read your conversion story about how it was in the church for you and why you left,If you are a convert what are the story's you heard from ex-Catholics,:ex:before I came into the Catholic Church I use to say things like "oh Catholics are going hell, that old man in Rome is not only a false prophet but IS the anti-christ,he should be ashamed of himself for trying to take people with him to hell,Catholics are worst than pagans,a bunch of idolaters",the Catholic church is "Babylon the great",,ect I could go on for days,Today, I'm in the Catholic Church after much study of the bible that made me see true Catholicism in it ,but many don't and I want to read it. like I said if you are an ex-Catholic ,I also want you to tell me two question I have for you (1) what are the 6 Holy Days of oblegation other than sundays?. (2) what are the 7 mortal sins and where is that in the bible ? GOD BLESS ,,,
