A Dua for When Everything Feels Overwhelming

Salam, everyone. I feel like my life is just falling to pieces lately. I've lost all hope and direction, and some of the people I loved aren't around anymore. My studies are really suffering too. I'm so lonely, as if there's absolutely no one there for me. I just feel completely lost. I'm turning to all of you for help-what's a good dua I can make to get through this tough time, to become stronger in my deen, and to feel closer to Allah SWT?
