Sleepless Nights and Anxiety Are Taking Their Toll

Assalamualaikum warahmatullahi wabarakatuh. It's morning and I haven't slept at all. While my family has been sleeping peacefully, I've been awake all night. This sleep trouble has been coming and going for years, but it feels worse now that it's back. Some nights are okay, but it's getting harder each day. With important exams coming up next month, I'm worried my lack of sleep will affect my ability to focus and study properly. The main issue is my anxiety - especially the worry about not being able to sleep. When I try to rest, my mind fills with anxious thoughts. This never used to happen to me. I know I should place my trust in Allah's plan, and I'm working on strengthening my faith through prayer and dhikr. If anyone has experienced something similar or has advice that might help, I would really appreciate hearing it. May Allah ease this difficulty for all those struggling.
