If I end my own life, would I face punishment in the Hereafter?

Salam everyone. I’ve been feeling really down, like a heavy sadness that just won’t leave me. It’s been this way for so long that nothing brings me joy-no hobbies, no plans, nothing. Even so, I force myself to keep going each day for Allah’s sake. I try to ignore those harmful thoughts, but sometimes it all gets too much. I end up hurting myself, and I can’t shake the urge to just… end it. I make du’a so often, asking Allah to take my soul instead of me doing something. Has anyone else been through this? What helps? I don’t know how much longer I can hold on.
