my heart’s not in salah anymore and it hurts

assalamu alaikum everyone. i’ve been praying since i was little, but i really started being consistent around 15. back then, salah came first no matter what. i’d sometimes cry after praying and just stay on the mat, talking to Allah. it’s been about five years now, but this past month has been rough. i find it so hard to get up and pray, even if i already have wudhu. my heart feels heavy with regret when i miss a salah, but i still can’t bring myself to do it. my iman feels so weak right now and i feel lost. i’m scared Allah will punish me badly. has anyone else been through this? any advice or duas would really help.
