Feeling too heavy to pray

Assalamu alaikum, I really need some advice. How do I overcome this feeling of heaviness that's keeping me from my prayers? Since the last week of Ramadan, my body has felt like a weight, and I've been delaying my Salah, sometimes even until midnight. The worst part is, I feel so empty inside that I don't even feel guilty about missing them. Does this mean Allah is upset with me? Could this be waswas from Shaytan? I feel so low that I sometimes wish to die, but I'm terrified because I know I haven't been fulfilling my duties as a Muslim. Time flies between prayer times, and every little thing feels so hard. My parents are trying to help, but nothing seems to work, and I hate disappointing them. I spend my days just lying in bed, doing nothing, and it breaks my heart that I can't even manage this basic act of worship. I see others sharing how their duas are being answered, and all I wanted was to grow closer to Allah and be consistent with my prayers, but I feel like I'm failing completely. Is it too late for me? How can I tell if Allah still has mercy on me? I just wish I could go back to the start of Ramadan when things felt okay.
