SOunds much like depression which comes along quite nicely with anxiety,
When you start getting horrid thoughts deliberatly turn your attention to something else, you dont have to have these thoughts if you dont want!!!!
Have you thought about or tried any therapy,its helped me loads in the last 6 months, it doesnt matter if you have suffered 10 weeks or 10 years anxiety is horrible period, so dont feel bad coming here for support, this board is full of great people.
Good luck babe, I hope things start looking up soon
