Losing weight

I have suffered really bad health anxiety now for about 2 years. Ive managed to self diagnose all sorts of tumours and terminal illnesses . I have been recently diagnosed with heart disease, which ironically isnt bothering me . I started a job at the beginning of Dec , Its a care job which ive done in the past but not for many many years. Anyway it was a week in the classroom (scary) , then straight out to work . It driving around in the evenings to clients houses , my hours are 6pm -10pm . I also work in the day 10am -2pm. i LOVE it !!! We always use to eat at around 6pm, so now that has changed to me eating earlier, all my eating has changed as my lunch is late, but now tea time is an hour earlier, and probably a smaller portion. Then obviuosly instead of watching TV on the settee all evening im out at work. I also have an an issues with my bowels which is being investigated , with my anxiety ive convinced myself its my pancreas. BUT my main problem which adds to my fear of pancreas cancer is that im loosing so much weight !!! ive lost just over a stone in 7 weeks.. I have been probabl;y a good stone and half over weight so loosing it wouldnt be of any harm, but why am i loosing it ? ..........is it the complete change of habits ? has this happend to anyone else .... im just making evertyhing worse. I just feel like im dying of some hidious cancer.

Fiona66001 ,what is amazing is your will power and how you continue to persevere dealing with all these issues,i truly hope that things will get better for you and it will .
I just got over an intense flu that at one point i thought i was not gonna make it and my anxiety did not help ,it just made matters worse and as i was recovering from the flu ,i was not able to sleep ,restless,panic attacks,anxiety and it was all due to a medication fluticasone ,a nasal steroid that totally made me more ill .
So now i have to get checked for sleep apnea ,because i have a shortness of breath when i lay down to sleep ,though i am in good spirits but in the back of my mind i am constantly stressing or in other words anxiety .
