Dear Welcome to HM We understnd your concerns I went through your details. I suggest you not to worry much. I sincerely do not see any problem with this except for your obsessive thinking in this matter. Everyone carries a song or some thoughts with them. Sometimes people sleep with a song lyrics in mind and gets up singing tht song next morning. Every day different songs come and go. All these are normal. Happens with everyone. But why are worried about it. Worry about some normal happening again and again creates obsession and obsession in turn creates anxiety. That is what you are in. Please describe the whole problem detail and post a direct question to me. Also include how this obsession caused loss of your job. I shall definitely help you with psychotherapy techniques to over come obsessive thoughts. Hope this answers your query. Available for further clarifications. Good luck.
