I haven't prayed in months and it's caught up with me

I haven't been praying since Ramadan left, I used to pray before this as well so I'm bit someone who's only religious during this month, I don’t know why I stoped or how it happend and at first I was fine, even now things are going really well for me but at night I feel really anxious I don't know why. I just get this pit in my stomach and music used to help it doesn't anymore. Even after a really good day I'll still feel anxious but I can't pin point what I'm feeling anxious about.

I want to start praying but I've been putting it off and slowly it's already half way through the year. I also feel like a fraud if I start praying again because this has happened so much and at this point if I seek forgiveness again and turn the page it'll feel insincere like it'll only be a matter of time before I stop again. So I guess I'm waiting till I can fully commit but now I'm feeling so anxious at night when I'm alone and I want it to stop.

I'm not sure if this made sense but I'm too tired to ask chat to correct the grammar sorry xx
