Read diary

Yes, alot did happen today. By what I'm going to write today, if anyone who knows me reads this, my identity will be revealed.
When I was discharged from the hospital four weeks ago, I had a psychiatrist from the hospital assigned to manage my care for about five months. He is a older man, past retirement age I'm sure! I'm really questioning if he is in the early stage of alzheimer's disease or something similar. About three weeks ago while in his office he was reading my discharge report on the computer. Or so I thought! He remarked on something in the report to me, and I said to him that the info was incorrect. We had a minor disagreement, and eventually he realized that he was looking at another patient's report, not mine. I went home and told my wife, and she said, "maybe he is losing it".
Last week he gave me a script for a sleeping pill, because I was having a hard time sleeping. I was given ECT while in the hospital and my memory has been affected. Anyway, I told him my GP prescribed me a sleeping pill. I forgot it was him that actually gave it to me. He said he had never heard of that drug, so he looked it up in one of his medical books. I went home and told my wife that he had never heard of that drug, only to have her say that he was the one who gave it to me. I also asked him about a CBT clinic they have in the hospital on the 11th floor, and he had never heard of that either. How am I supposed to get anything out of this patient/doctor relationship when I'm questioning his capability?
After my appointment I went and had a visit with my mother. I left however, feeling really depressed. As said as it seems, I really think my mother is a trigger for my depression.
Another trigger is my work. While in hospital my store closed, so I chose another store to work in. No one told me however that I wouldn't get many hours there. I inquired at another store about the possibility of more hours. Anyways, to make a long story short, I've been out of the hospital about a month, and haven't yet gone back to work. I'm positive that this is contributing to my low mood. Now I'm thinking that all I have to do is go back to work, and my depression will go away. I hope I'm right, because my thinking has got me believing that if I dont have a job, I'd be better off killing myself.
