It is hard to say what makes a person struggle with an anxiety disorder. Some say it is related to genetics, some day it's environmental factors, others say it is learned behaviours. There is more information on this in the program and education sections if you are interested. Just know that anxiety does not define you and just because you are struggling with it now it doesn't mean you are destined to feel anxious forever. With work, support and knowledge you can make a difference in your anxiety levels.
What session are you on in the program? The farther along you get the more understanding you will gain of your anxiety and how to manage it.
Since we are on the subject of perfection in another thread I thought I would bring it up here. I know you said you are capable of doing the work, but are you too capable. Are you possibly the one putting the load on? Is it possible your colleagues are talking about you because you are making them look bad?
I know also from personal experience that if you are good at something you will be given more work of that nature. To the point where you can't finish and keep up the quality. So I had to balance things. Temporary doesn't need the quality of something permanent. But it is hard to do if you are a perfectionist.
Do you get panic in your routine work because you fear you will be given more work and you will have to do it with less quality than you would like. That it will then be less impressive to those you want to impress. Even though it will be most likely still good, just not good enough for you. Are you possibly your own enemy.
My past history of depression dates back to 1997 when I was senior school boy.I came to discover about myself that I get panic in my normal routine work.As for example I find difficult myself concentrating on my work.I find difficult in conversation with my senior because I feel less confident about my work.As soon as I am loaded with work I start getting panic.I feel myself unable to perform good in time bound work where there are work pressures.I get hurted & upset very soon if any of my colleague says something negative directly to me or even at back side.
Now if I analyze above situations,they are very normal & every human in this world face these challanges. But why I get panic on such normal circumstances?Is it a personality disorder or how can I interpret myself because I feel myself getting depressed & anxious for no reasons.
