Sounds like mania to me. When I was religious I would become super-religious when manic. Be careful as I lost friends this way as I would not shut up about Jesus. It wasn't like that all the time when I was religious, only when manic did I go way over the top. I also believed God healed me of mental illness and gave my testimony so when I became ill again I was in denial as I was still convinced I was healed. When I finally had a breakdown everything fell apart and I lost friends. I felt like such an idiot giving what was a false testimony. Some Christians judged me as having done something wrong as I 'lost' my healing. It broke my heart and I lost my faith.
Not to scare you though. I hope you can keep your faith in a balanced way. Take care
