Dealing with Emptiness and Fear in This Temporary World

Assalamu Alaikum wa Rahmatullahi wa Barakatuh. Lately, this dunya feels so temporary that it’s hard for me to enjoy anything, even the halal things we’re allowed to do. I feel hollow, ya know? Like, what’s the point when it’s all ending soon. This emptiness just hangs over me, and I don't know how to shake it off. Then there’s the fear-always wondering if my deeds are enough. I know Allah is Ar-Rahman and sees my efforts, but I get so scared of jahannam. It's like I can’t find the balance between hope and fear. This worry follows me all day, every single moment. Has anyone else felt this? How do you cope with the emptiness and the constant fear that you’re falling short? Jazakum Allahu Khairan.
