Thanks for writing to HCM
I think you need second opinion
of another surgeon before referring to you a psychiatrist
You need proper clinical examination and investigations.
Investigations include routine hemogram,RBS,LFT,Urine RE/ME and ultrasound
of abdomen, CT Scan
may be done if needed .
These investigations and clinical examination can confirm that you have disease or not, then you may be treated for psychological aspect of illness.
Get well soon.
