Going through the same process now too, it is a mental game more than anything. But everyone feels the same and it's not your "fault"! I try and forget about my application as soon as I have completed the most recent task, just note it down in your application tracker and move on to the next, if you get through to the next stage, great! If not, you have started another one. You will land a position in time, you just have to carry on and trust the process.
