My faith is crumbling

I don't even know how to begin this.

From day to night it's like some switch flicked and everything went down the drain. I'm having a crisis, the damn WW of spiritual warfare

I've started questioning everything I've ever believed, am i repenting the right way? Have i received the Holy Spirit? Am i saved? Do i actually believe in this or im just lying to myself? Can i actually believe in this? Am i trying to follow God out of love or because the idea of eternal damnation rooted itself so deep in my mind that im scared of being damned?

I don't know what's wrong with me, I can't even stop lusting.

Im so scared of not being saved yet. I want God, i want to trail the narrow path, i want to be right, but i don't know if i actually believe in this and submit 100%

I know the reing isn't for everyone, but it's just a matter of choice, isn't it? If i try, i can be a true son of God, why can't i just do it??

Im tired of these doubts, im tired of this fear.

I need guidance, please. I want this love
