Thinking of returning to my faith after stepping away a few times

Assalamu alaikum. I just feel this strong pull to come back to Islam, even though I've left and come back a few times already. I know, deep down, that Allah is where I truly belong, no matter what's going on in my life. And honestly, life hasn't been bad since I stopped praying and fasting regularly-it's actually been pretty good in some ways. But that just makes me feel more guilty inside, like I'm drifting away. Sometimes I worry that this comfortable life is a test and a distraction. The biggest struggle for me has always been feeling alone and like I don't fit in, plus some personal anxieties (which I know I probably make worse by overthinking). Yesterday, I was remembering all those times I left and then returned. What always brought me back? It was this deep need to belong somewhere, to feel understood. And yesterday, out of nowhere, I felt this incredibly strong connection to Allah. I can't even explain it properly. I felt silly at first, like 'why would He welcome someone as inconsistent as me?' But the feeling was real. I felt like a small child, alone, and then sensed a comforting hand of mercy. I spent the whole night in thought about Allah. My early years were tough, but I'm starting to see maybe I needed those experiences. I'm reaching out because I was hoping you could share some ayahs from the Quran that speak to feeling isolated and like you don't belong? I really want to remember that He is always with us, always watching over every single person.
