As-Salaam-Alaikum, sometimes I push off salah and it leaves me feeling so down

I don't dislike salah, and I don't deny its importance, it's just that when the time comes, I feel so mentally drained. I spend most of my day just scrolling through my phone. When the adhan reminds me it's time, I tell myself 'I'll pray in a little while,' and then before I know it, the time is gone. In that moment, it doesn't feel like a major slip-up. But afterward, I feel terrible, filled with guilt and disappointment in myself. I also find it hard to focus on studying or even sitting quietly for tasks that need my full attention. Sometimes I think, is this more about my mind being constantly overstimulated, or is it about my iman? Has anyone else experienced this? How did you find your way back to being consistent without just leaning on fear or regret?
