I'm Trapped

The random generation put me in a corner with no way out. I've searched this small area for 10 minutes and there is nowhere to go from here. This is where I will die and lose my best kit ever :(
Has anyone else experienced this or did I just get extremely unlucky?

Edit: There is no secret lever to escape this area. Check the interactive map. There only exists one lever in this module and it doesn’t lead out. The only lever in the module is the lever which opens the false wall after you drop down into the pit with the three chests. The lever allows you back INTO this module, not out. And it is the only lever in the module. Please do bare minimum research before ignorantly commenting “you missed the lever 🤡 “
