Struggling with Faith and understanding is God real?

I find myself struggling I was confirmed 2 years ago, and yet I still struggle? Before reaffirming my Catholic faith I had struggled with worldly desires. Wanting them, and now that I’ve consecrated myself further in my faith by getting confirmed it seems those worldly desires are closer then I thought closer then I imagined?

I struggle to wrap my head around is the church real? Are we just people who are in a false belief? Why is the world so evil? If we are the true church why do we feel trapped when talking about the faith to Protestants?

It hurts like defending our mother, and then next thing you know a Protestant friend will be like she wasn’t a virgin Jesus had brothers, where does it say that in the bible, the Eucharist isn’t real, etc etc. and I show them all the same things we Catholics believe and what scripture readings support it and it doesn’t feel enough?
•
I see videos of priests referencing the catechism of the Catholic Church, saying that there is no salvation outside of the Catholic Church. But what does that say about our Protestant or orthodox brothers and sisters?
•
Are their lives any less just because they didn’t believe in the Catholic Church? How can we defend certain relics like the Veil of Manoppello which clearly does not look like christ.
•
In the case of liturgical abuses too it’s like how do we defend the essence of what Catholicism is and teaches to a world so far from God?
•
God has given me miracles, I know he’s real I just I’m struggling to bow down? I struggling to submit. Is it stubbornness? I don’t know am I thinking too much about it? I don’t know? Everytime I go to confession something bad happens and then I go back into the same sin. And the cycle repeats over and over again.
I feel tired? I feel lost?
•
I fear having a real good true confession because it’s hard to confess when the priest is staring right infront of you and you know that it is not the priest who is there but God in his presence and eminence. And I feel weak.

God help me.
