Why do I feel so much panic about the afterlife?

As-salamu alaykum. I’m a sister who was born into Islam, Alhamdulillah, but since I was little I’ve had bad panic and anxiety attacks. I sometimes start crying from sheer fear when I think about death and what comes after. I’m scared of both Jannah and Jahannam - not because I don’t want Paradise, but because the idea of existing forever terrifies me. The thought of death and then eternal existence makes me panic more than anything. Because of this fear I sometimes avoid salah and reading the Qur’an, even though I keep Allah in my thoughts when things go well or badly and I thank and rely on Him. It’s just that thinking about the ultimate end and what follows this dunya triggers deep panic, not a doubt that I won’t make it to Jannah. The feelings get so intense that I’ll go to my mother for comfort; Alhamdulillah she’s been supportive since I was young. Still, I hate that this fear around such an important part of Islam pushes me away from worship. I find myself asking why Allah made me like this. It makes me question myself and even why I was born into this faith. If anyone has tips, coping strategies, or has felt the same way, I’d really appreciate hearing your experience. Jazakum Allahu khairan.
