I too am a Catechumen in Portsmouth, hoping to be Baptised quite shortly. I come to Orthodoxy at a late age, so be of good cheer, there is no reason to have any misgivings about your past experiences (or otherwise). I am certain you will be delighted by the reception you get whenever you attend one of our meetings.
The Wednesday prayer meetings are not at St Faith's church, but in the home of one of our ministers. I suggest you contact him to get details. He is James-Antony Kelly, 078 5493 6328.
Sadly I shall not be there tomorrow because I am away this week, but I look forward to meeting you next week, all being well. In the meantime rest assured of my prayers.
With love and prayers,
