is it easy to become a better muslim?

assalamu alaikum, ive been reconnecting with my faith more lately because of my mental health struggles. i grew up in a very religious home but wasnt really taught the why behind things - it was more just told to me without much explanation. so i drifted away for a few years, astaghfirullah, though i never stopped considering myself a muslim. i dont feel like a ‘good muslim’ yet since theres a lot i need to change and ask forgiveness for, but im trying to learn more to strengthen my iman. i deal with waswas a lot (even outside religious matters), and that pushed me closer to Allah swt. those whispers make me doubt my sincerity and worry whether Allah will accept me, especially since anxiety and overthinking distract me during prayer. im trying to read the Qur’an with translation and tafsir, pray five times a day, remember Allah swt, and increase my knowledge. i also want to follow some trusted scholars to learn more. but sometimes i feel like it might not be enough. is being a believer really that simple - just pray five times, remember Allah and the prophets (peace be upon them), study the Qur’an and try to live by it? i hear people talk about the akhira and the grave, and that scares me because i wonder if im doing enough and truly on the path of the believers, or if shaytan is just misleading me again. i still sin, and may Allah swt forgive me, but i think im doing it less and with more thought, which has reduced how often it happens. if i keep doing what im doing now, will that be sufficient? jazakAllah khair for any advice.
