Feeling Called to the Shahada Yet Hesitant...

Assalamu alaikum, everyone. My heart truly believes there is no god but Allah and that He alone is worthy of worship, and I believe in all the prophets. But I’m held back by this nagging feeling-what if I’m mistaken? What if I regret it later? Is it okay to say the shahada alone in my room? I don’t know Arabic, I don’t know how to pray yet, and I carry some bad habits. I know Muslims aren’t perfect and can still have sins, but… I’m just unsure. Will it even count if I have these doubts lingering? I think about praying salah every single day but just can’t seem to take that next step. Honestly, I can’t fully explain why I haven’t embraced Islam yet. I want to, truly, but the fear of being wrong or turning back later keeps me frozen. Please make du’a for me.
