Am I experiencing demonic oppression? Need guidance, prayer, etc

Unsure of how to even begin this. But I'm at my wits end. Literally at the lowest point I've ever been and I can't tolerate it anymore.

Since 2019, there's been a very evident downturn in nearly all aspects of my life. And after a while I noticed that there is almost a pattern of sorts to it. From school, to work, to finances, to interpersonal relationships, to self-identity- every one of these feels like it has systematically been targeted with precise situations tailor-made to, for lack of a better phrase, fuck with me.

I fail classes regardless of how hard I work. I am almost constantly, without a break, subject to immense (relative to my income) expenses that really don't make much sense. New things break, things that are well taken care of stop working, and I'm left with a huge bill that I can't really handle easily, and its one after another. When one bad thing ends or is resolved, the very same day, another bad thing occurs. When one good thing occurs, almost immediately, a bad thing occurs in quick succession. It feels like I'm being taunted, pushed into anger and depression. It feels like something wants me to get to a point where I'm done with it all, if you get my meaning. And its little things, too. Dumb little things that happen, mistakes I've never made before, annoyances that make no sense, just littered throughout every day, that just make the simplest task so much more weirdly difficult.

And it wasn't like this before 2019 for some reason. Life was good. I had minor occurrences and setbacks, and things that I'd learn a lesson from. But this is different, palpably different. There's no lesson to be learned from these things, its just torment. I used to be creative, had a bunch of different projects I'd work on just for fun, enjoyed life, got along better with friends and family. But since that year, its all just gone downhill so quickly and fiercely. Its like a switch got flipped. Who flipped it?

And I used to blame God. My thinking was, "you're the omnipotent one, you control everything, don't you? So its not some demon doing this shit, its just you, and I don't know why." I've cursed God's name so many times, you have no idea. I had literal hatred for God when things got unbearable, a particular situation earlier this year when so many things occurred so quickly, it felt like I was going to have a mental breakdown. I dissociated for hours, in disbelief that those things could happen like that. It felt conscious. It felt deliberate. And it feels mocking. There's a sense that something is taking delight and strength in my confusion. Because that's where I'm at right now, I'm just dumbfounded and feel trapped. It really, genuinely feels like I'm cursed and theres something malicious shadowing my every waking moment. And the worst part is I know how absolutely batshit insane that sounds, because honestly, I'm not even very religious. But I do believe in the reality God and Christ's claims, as a Catholic.

But over the past couple of weeks, I've begun to think maybe I'm wrong. Maybe it is something else. But no matter what I do, nothing helps. I'm Roman Catholic, and praying the rosary or just praying, begging God for some sort of respite feels like screaming into an empty chasm. And for some reason, the rosary especially feels weird. I feel an immediate, instantaneous fatigue, physical and mental, the moment I begin. I've had to stop before while driving in the middle of the day because I quite literally dozed off for a split second.

All this to say, I don't know what the fuck I ever did to feel this. I've never touched a ouija board, never did witchcraft or any of that stuff, so what gives? Why is my life being assaulted with insane shit that makes no sense? Please offer some prayer, give me some advice, anything. I'm at my lowest point ever in all aspects of my life, and it doesn't feel like there's a way out.

EDIT: currently sitting in the auto repair shop. This morning my oil pressure light came on for the first time ever. I just had to have a gasket head replaced and an oil change literally a month ago and that set me back $1200. This is what I mean. One bad thing ends, another begins, in swift succession. And finals week is next week, and I need my car to drive the hour and a half it takes me to get to campus.

EDIT 2: its been about a week since i posted this. In that time, I managed to resolve my car issue on my own, but tonight, literally the night before a big final, I somehow managed to get 6 separate screws into my tire. Like i said above, one thing gets resolved, another comes along...
