Struggling with Sadness – Do You Know Any Helpful Duas?

Assalamu Alaikum wa rahmatullahi wa barakatuh. Ramadan and Shawwal were good for me, but after moving to a new place, I've been swallowed by this heavy sadness and low energy. I can't remember when I last slept well. My health problems are weighing me down, and because of how I feel, my health has gotten worse. I can't focus in salah, haven't stepped outside for walks in weeks, and I feel so distant from Allah. It's like shaytan is pulling me in, and the urge toward secret sins is breaking me. I don't know what to do, and I feel awful. I tried turning to my family, but they don't understand-maybe they just can't help. It's not their fault. I take refuge in Allah, the Most Merciful, and I'm asking you for help. BarakAllahu feekum.
