How to be on fire again???

So lately for the few weeks since I’ve been home from university I’ve been feeling very angry and bitter and not happy about my family situation and I think that has led me to be stagnant in my faith. I go to church but I barely pray or read the word as I used to and I’m not sure how to get back on track and be on fire for Christ.

I love God so much but I’m confused about some things and it’s making me loose faith and hope in those things

Any suggestions on how to be on fire again .
