Hi Cat herder
I think it will help if you can learn the skills needed to be able to cope with guys like this so that you can do what you want in life.
You symptoms are your reaction to your anxiety caused by the lack of confidence needed to be able to deal with what this guy is doing to you. If that makes sense.
If You work on your confidence to be able to deal with him and anyone else like him, this will ease your symptoms and the anxiety caused by them.
There are two types of anxiety, somatic and cognitive. Somatic anxiety refers to individuals perceptions of their physiological state in response to the stressful situation in which they find themselves. Cognitive is characterised by fear of failure and negative expectations about things.
Dealing with this guy is about learning to rise above and beyond what he is trying to do so that what ever he throws at you it can be dealt with without the anxiety of failure or of your reactions to him. Bullies like to know that they are making an impact on your life, it fuels them to carry on.
I know it will seem easier just to give up and change your whole life over it, but it will not be in the end, you are running away instead of learning the skills to cope and to make you believe you are stronger.
Bullies have a knack in making you feel like you do, that is what they are trying to do. But only you can allow them to continue one way or another. I hope that makes sense.
Is there anyone in the office who you can say to ' look this guy is really upsetting me with his cyber bullying can you come and see what he is doing and how can I ban him from contacting me again.' ? Taking the control back and showing you are staying strong, but still are willing to accept help is the power.
Here is an article that might help you see things differently. :)
