Finding My Way Back to Allah

Assalamu alaikum. I'm reaching out because I feel so lost. I was in a relationship that wasn't right-it was haram-and it ended because we had different faiths and our families wouldn't accept each other. Since then, I've been feeling far from my deen, like I've been away from Islam for too long. But when I pray, I feel this calmness, this peace, and I just want to feel that again. I'm trying to come back to Allah, but I don't know where to start. Any advice or encouragement would mean a lot. JazakAllah khair.
