Finally found a programming job. Now I have week and half off between jobs, got a question.

Okay so I was working in a call center for the last 9 months. During that time I was tired all the time. I'm not really sure if it was because it was my real first full time job or if it's just because I'm dealing with people all time. So I'm not sure if it's the full time job that drained me or dealing with the people. I am a introvert so in theory the dealing with people should be what's draining me or maybe the stress from dealing people, but I'm not totally if the same thing will happen when I start my new job. Is just going to be normal life for me?
