Why cant i go to work anymore as im to scared and keep making myself feel ill

Can't say: This is obviously impairing your ability to function normally & you don't have the skill set to deal with it. You need to contact your doc and discuss the issue, you may be ill, in not s/he can refer you for help. A therapist or psychiatrist can teach you the skills needed to get back on track while they explore with you the reasons you got where you are now.
