Starting over is like being reborn, give yourself time to learn again, to feel again, to live your faith again. Take out the books that you have read before and learn something new from them. Find freedom in the search and don't push yourself too hard. Knowledge and love will return as you let them in. I was out of touch with my faith also, and it takes time to regain what we have let go. Just be patient and in time your faith will become even more to you than what it was.
