Importance of the RIGHT JOB.

Today, I finally realised how important it is to find a job that suits you, and that you enjoy doing. Because I just landed myself in a good job, but not one that suits me and I do not enjoy doing it. It's good because of the rare opportunity and pay, etc.
I feel like crap at work. Because the work I do doesn't give me a sense of satisfaction or achievement. To me, it feels like doing useless work. Because I don't learn anything from it. What makes it even worse is the environment that this job doesn't allow me to be in the frontline - getting to communicate with other humans. I mostly do paperwork. I feel very restrained and confined. I am a person who needs to be OUT THERE talking to people, that's why I chose to pursue public healthcare as my future. But this temporary job is so desk bound, which akins to an OFFICE LADY. I just can't handle OL jobscope. 
I feel very regretful now, to not think twice previously when offered this temp. job. What was I thinking then? Everyday I have to psycho myself that the day will soon pass and a new day will arrive. But the same old day will arrive. So it sucks.
I am dying for interaction. I want to be out there helping out, even if it meant doing 'sai-kang' or literally shit job that requires a lot of labour work. I want to be able to be of help. Like how a sales staff would be of help to a customer that comes to shop. Or a customer service officer who replies email and knows that the email would sort of help the sender.
& also I don't have a guide at work, and everyday feels so lost. Not knowing what to accomplish each day. I am the kind of person who needs to accomplish something each day. So this in turn has led to the stress that I am experiencing after only 4 days of work. Maybe it's just too different from the kind of work I did before. It's so hard to look forward to each new day. I am really tearing as I type this post out, that's how much stress and sadness I am facing. I don't even know what to do with this job. My mum wants me to try it and only give up when it becomes too much to handle.
Now I know how sucky it is to be in a job that is so not you and having to hold on. But I am slowly losing the will to hold on, because I don't learn much from it. Maybe I crave interaction, knowledge and skills a lot, I am greedy for these. But there is really no job satisfaction, not sure how long I can survive. I have 50+ working days.
