When I Stumbled and Felt Lost

Assalamu alaikum everyone. I was in a really tough spot, pouring my heart out in dua and tears to Allah, but somehow, things just seemed to get heavier. My iman felt weak, and I fell back into a mistake. Now, I'm sitting here feeling like I totally failed a test from Allah, and that this harder situation is a consequence of me not holding strong and slipping up. It honestly feels like I've damaged my connection with Him, and I keep thinking, 'I shouldn't have let that happen.'
