Thing is because you were raised with Islam, you feel bad for not praying because of your minds been programmed, it’s a guilt mechanism.
I still believe in god, not sure what religion I follow except the spiritual side of Buddhism (not it’s prophecies and gods though, just it’s teaching on life like how to be happy, connect with yourself, be calm, etc etc.). I grew up fairly non religious, although I did have Christian and Muslim influences, then at about 8 my mum converted to Islam (from a not bothered Shi’a to a fairly strict Sunni), I never enjoyed it. My dad wasn’t fond of it either, I’m glad for the happiness it’s given my mum but I struggle explaining to her that not everyone can find that happiness in the same place. I still respect the religion, it has its upsides and downsides although most people seem to only have knowledge on the downsides these days (they do somewhat outweigh the upsides).
So yeah, I think you just need to disconnect and find a purpose then see how you feel. I found it a lot easier when I moved in with my dad, there’s no religious influence so I was free to make my own choices - and I didn’t give up on Islam I gave it a try and studied it, that’s what ultimately made me realise I have no bond with it. Also not fond of most people in the Muslim community. I’ve always believed religion should enhance your life and not dictate it.
