Struggling with Doubts About Allah's Help

Assalamu alaikum everyone, I need to get something off my chest. I've been dealing with some serious tooth issues, all because of my own mistakes, and it's really taking a toll on me. The anxiety is getting overwhelming. In the past, I'd have just trusted that Allah would take care of it without a second thought. But now, for some reason, these problems feel permanent, and it's shaking my faith a bit. I know deep down that Allah can fix anything, yet I catch myself doubting His power for the first time ever. It's confusing because I truly believe in Islam, but every time I think about my teeth, I get this sinking feeling like maybe this is beyond help. Lately, I've been so anxious and sad, and even small things are affecting my daily life. It might not seem like a huge deal, but it feels like everything's on hold because of this. Part of me worries that Allah won't assist me, especially since I slipped up on a sin I'd promised to avoid-even though I've repented and made kaffarah. And because I caused these problems myself, it doesn't even feel like a test, just a consequence. If anyone has any advice on how to handle this, I'd really appreciate it. JazakAllah khair.
