Hi Kelly
I know exactly what your feeling. I have OCD and also have really bad intrusive thoughts. I am on medication and it works pretty well on my OCD also but, like you, I get to worrying that I am dying....all the time.
I have been staying in a hotel for the past month waiting for my house and my throat has been very agistated and sore. At night I have these terrible coughing spells and at times, I am convinced that it is cancer. I keep thinking that. It is terrible. Then, like you, thinking and talking about it makes it even worse. Rationally, I know that I am in a dusty hotel room and that is why I am having coughing spells and my throat hurts because during the day, it doesnt happen and I usually am gone out of the hotel room during the day.
I know that your having a hard time with this. I totally understand. Your not alone. Hang in there and post as often as you need too.
Hugs,
jen
