There is a call center in my city too. I know at least three people who worked at it without mental illnesses who either had breakdowns while at work (one guy just ran out of the building and just kept running even though his car was in the parking lot) or developed some sort of depression. It is not you, it is the job. Just keep that in mind. I'm glad that you are taking steps to get out of this situation. It seems like 60% of people in the world are jerks, so it is hard to avoid them. I understand not being able to quit until you have another job. Keep trying and you are bound to get something else eventually. Every week you are one step closer to getting out. Where I live, the economy is getting better and better. Hopefully the same is happening in your town as well. Keep us posted on how it's going for you.
