Dear Kyle and Nicola.
I would also like to extend my welcome to you o this forum.
I am a Catechumen of the Church in Portsmouth, attending with Antony-Paul and Fr. Simon, and can safely and honestly say that I have found myself extremely comfortable with all here. I, as well as many people here I imagine have done things in our lives that have made us worry about being judged by the church. As John already said, we are a a Church, a spirtual hospital, not a inquisition.
Remember that though you may seem nervous about how you are recived you are among equals, all human. I for one welcome you with open arms, and pray you will find in Orthodoxy what you are looking for.
With love and Prayers,
