How Can You Feel Certain About Islam's Truth, Even After Losing That Spiritual Connection?

Salam everyone, I wanted to share something heavy on my heart. There was a time when I prayed all five salah regularly and felt close to Allah subhanahu wa ta'ala-it gave me so much peace. I find myself missing that feeling deeply, and now, no matter how much I try, I can't seem to get it back. It’s like it's slowly eating away at me from the inside. Does anyone else ever struggle with this?
