How to overcome a spiritual rut and a feeling of emptiness in my heart?

وَبَرَكاتُهُ‎ اَلسَلامُ عَلَيْكُم وَرَحْمَةُ اَلل I am a good Muslim, or so I hope. I always prayers on time, read Quran, don't listen to music, and am kind to my family and friends. However, recently I have been feeling nothing in my heart when I am reminded of Allah SWT unlike how I used to before. I feel like I'm looking for the approval of people now more than ever before. And recently I had sinned, yet I felt nothing. I still repented, of course, but I fear where I'm heading if I stay like this. I felt no guilt for the sin I committed and had to force myself to feel any sort of emotion. I really need help on this matter. جَزَاكَ ٱللَّٰهُ خَيْرًا
