Is it normal my dreams told me i'm worthless

So about 2 months ago I had this crazy dream that was really deep and I woke up crying because, at the time, is was literally the most beautiful thing I have ever experienced. since that dream I was fascinated and in love with dreaming. So I began keeping a dream journal. I recorded the dream on paper immediately. however there were some details I couldn't recall. Like who this one person was at the end of the dream. She was very important to me in the dream but i couldn't describe her.

So about a week ago I had some very emotional things going on in my life and have lost contact with some very special people. The situation left me hopeless.

Just the other day I had another really amazing dream but this one was really sad and depressing. This dream too, had me wake up in tears. it was about the special people that I was involved with and it filled in all the details that were missing from that first incredible dream.

So, now having all the whole picture painted, I realize who the missing face was in my first dream. It all clicked into place. both dreams completed each other and recreated everything that had happened to me emotionally in the time between them. And the literal message that came from the last dream I had told me that I was worthless, a coward, a nobody, a pest to society and all my friends, and that I ruin opportunities to form bonds with people

And I suppose the unfortunate truth is that I agree almost 100% with that realization.

So I guess I have a few questions.

Is it normal for dreams to:
(1)make you wake up crying because they are either wonderful or terrible?
(2)Say bad things about you and degrade you as a person?

and what should I do about all of this? Ever since that, almost enlightening dream, I have been depressed and pushing all the people I love away from me.
