I have been in the same situation. And most of them was cause by people who are around me. And I've struggled for like 3 years and I came to the conclusion that " you know what God does not exist " but long story short I was seeing the God that people created and not the God inside the bible so my faith was weaken. Then I gave myself time to fist to truly know him instead of praying or going to church ot doing whatever I'm supposed to do. Then I realise if I didn't know him everything will be worthless and Iean even my prayer and everything I do to worship him. So I gave me and him time and got to know him and now no matter what I send firm in his word and from that word I know to pray I know how to worship. Maybe if you want I can help you get through it.
