Hi. I'm 21F with a diagnosis of anxiety and depression. I landed my first job 6 months after I graduated from college. I was very excited but all that excitement vanished on the first day - actually, no the first meeting.

I was offered a job by a very big and famous company. I accepted and on the first day, I found out that the actually it's a child company of the big company (which was never mentioned in the offer letter). Also, in my team there is only me, another person and supervisor. They barely have any people there. Their HR dept is almost empty. 

Also, today was the second day and I was assigned to work on a project. without any training. I am an engineer. They literally asked me to work on a project on the second day. I mean this is my first job. 

I have been having a really scaring feeling since yesterday and today it was even worst. I have lost my appetite. I have heart palpitations and chest pain. It's been two days and I have decided I need to quit.

I am so worried about my parents and my relatives, what would they think. My parents were so happy for me when they found out I got a job. I feel like such a big disappointment.

I don't know whether my decision is due to the anxiety or not. I am also anxious that I may regret all this. I feel stuck and don't know what to do.
