How can I deal with my spiritual anxiety?

Salam everyone. I embraced Islam around two years ago, Alhamdulillah, and things were mostly fine. But lately I’m having strange thoughts that make me feel like I’m losing my mind or that something is wrong with me. As I explore more about Islam, more questions pop up. I heard a speaker once share a personal moment where they realized Allah is everywhere and always the answer. But when I reflected on it, I struggled to truly accept it. Also I watched a video where a sister asked, “Do you honestly believe in Allah?” and that alone gave me so much anxiety because I’m not sure about my faith. I think I’m dealing with serious doubts about Allah, and they keep coming back, making me feel like I’m the issue or failing. To add to it, I’ve had a really hard time making Muslim friends so I have no one to talk to about this, which makes me feel isolated and sometimes I spiral, worrying I have mental health problems, and then it leads to one worry after another. I honestly don’t know what to do. I’d really appreciate any advice you could share, may Allah reward you, Insha’Allah.
