As a Revert, I'm Seeking Advice on Prayer and Strengthening My Iman

Assalamu alaikum, everyone. I'm a revert, and my family isn't aware of my conversion-it's something I have to keep private for my safety. Lately, I've been having a hard time with my salah; I miss a lot of prayers and often end up making them up late at night. Even when I do pray, my focus drifts, and I feel like my iman is really low. I can't visit a masjid for guidance, which makes it tougher. I try to read Quran and do zikr, but I worry it's not enough. Any advice or encouragement would mean so much to me. JazakAllah khair in advance.
