Assalamualaikum - Feeling Distant from Dua, Need Advice

Assalamualaikum brothers and sisters, Before you reply, please read everything - I really need sincere help. A bit of background: I’ve been making dua for many things for a long time, but I’m not seeing them happen. I’ve made dua for others too, and I know the hadith about angels praying for you when you pray for others, so I asked my mother to make dua as well. But it feels like everyone else is getting what I asked for, even people who didn’t work for it, while I keep grinding day and night and have made countless duas without results. To make it worse, the people who doubted me or treated me wrong seem to be living their best lives and getting almost everything I wanted, without effort, and just being happy. That disappointment pushed me into a slump. I started missing college lectures, delaying my salah, and sometimes praying all my fard salah at once around 11 AM instead of keeping them on time. I know the teachings: we shouldn’t be hasty in dua, we should have sabr, return to Allah, and keep asking. I know the feeling of being so let down that it’s hard to turn back is wrong - I’m saying istighfar even as I write this - but honestly I can’t force myself to make dua. It feels heavy, like I’m too disappointed to speak to Allah. I’m not looking to complain. I really need guidance. If any of you have felt this kind of bottled-up negative emotion toward Allah and nearly gave up, what helped you come back? What practical steps or reminders got you to pick up your salah and dua again? I’m open to any sincere suggestions. JazakAllahu khairan.
