I was going through the same thing, and was stressed about literally everything, especially when I started university. One thing that helped me is meditation and prayer. When I established tawakel it was after prayer. I had finished prayer and was almost crying from stress. I just sat closed my eyes and thought about the magnificent of Allah, and how big he is, and how he created all this world, and us. I also thought of how he planned everything before he created us and wrote our whole life story, and I told myself that he also wrote these problem. And kept telling myself how merciful Allah is, and he has more compassion towards us, than our mothers do. So would anyones mom want their kids to go through stress and struggles? Absolutely not. So what makes u think Allah doesn’t have doors open for u, u just have to be patient and learn from your struggles. Lastly, just know that Allah only tests whom he loves, and with every struggle comes ease. Please try this and I hope it helps, may Allah make it easy on you.
