Back and Forth, and only Back again...

The decisions that I make seem to only cast shadows over me, as I mope with my head down. I let go of the controls, and my instructor is left with the responisibility to fly this gigantic aircraft we call life. We fly into the clouds, without any approach plates and without any knowledge of how to get back to the airport. Lost in depressive conditions, one of the worst situations a pilot can be in. The GPS is malfunctioning, and our instrumens don't match up to the maneuvers and headings we turn to. It seems as though, there is no way we are going to land safely. We are without situational awareness, and I just give up. I gave this aircraft a shot, but I am just exhausted. As a professional pilot that he is, he tries to guide me through his actions. He kept calling up tower on different frequencies, tried to fix the instruments, turned on the pitot heat, and tried restarting the GPS monitor multiple times, while trying to keep his head high, even though it weighs another ton from all the stress and depression. He tries to give me motivation to aid him in troubleshooting this aircraft, even when he is at such a low altitude himself. I can only tell him that I can't right now. I tell him I'll be back in January to fly. I don't know what else to do. So I dial in 7700 on the transponder, call in on 121.5 emergency frequencies and ask for assistance.
