Feeling Alone in My New Journey as a Muslim

As-salamu alaykum. I reverted around Ramadan in February after asking Allah (SWT) for a sign, and I felt He answered me. Lately I’ve been feeling pretty alone. I’m the only revert I know nearby, and the closest masjid is about a 45-minute drive away. Last Ramadan I didn’t feel this loneliness - I had a friend who introduced me to Islam and gave a lot of guidance. We had a falling out, and I don’t think he’ll be around for this coming Ramadan. I wish I’d had the chance to thank him properly for guiding me. I make dua for him and pray Allah blesses him in this dunya and the akhira and that he can forgive me. Since we drifted apart, I’ve been more consistent with my prayers, even tahajjud some nights, but I still have many questions. I work nights and sleep during the day, so waking up for the daytime prayers is really hard. Often I combine some prayers before I go to work, and I feel guilty about that. Also I’m not always sure I’m praying correctly - when I start each rakat I recite Surah al-Fatiha; is that the right practice? I’m a little nervous about going to the masjid - I went once and everyone was kind, but I still felt out of place. Any practical advice would mean a lot: tips for managing prayers with a night-shift schedule, simple ways to check my prayer is correct, or how to feel more comfortable at the masjid as a new revert. JazakAllahu khayran for any help.
