Trusting Allah More Deeply

Salam everyone. I'm really struggling and could use some advice. How do I actually build stronger tawakkul in my heart? Lately, life's been so heavy-I can't sleep, and sometimes my body just won't accept food. It's like my worries are eating me alive. I try to remember Allah is with me, but it still feels so hard. Please share anything that helped you. Jazakum Allahu khayran.
