Stomach pain - for no apparent reason?

It has been about a year now that I have a stomach ache. I did every possible test in order to find what causes me pain, but nothing was found (ultrasound, stool sample, several blood tests and gastroscopy). Nothing was found in any of these tests and it makes me even MORE worried.

Doctors suggest I should see a therapist in order to find if this pain is caused by something mental (anxiety or other mental disorder).

I feel helpless. Although I really wish I could believe my doctors telling me I am completely healthy - I can’t believe them. I feel like my stomach is being stabbed in a specific spot but I have nothing there. I also feel that what may cause my stomach hurt so much is the fact I constantly pinch it in order to find “growths” or “tumors” - while I obviously don’t know anything about anatomy (I may feel veins or muscle tissue or anything). Maybe it’s the constant pinching that cause the constant pain and stop it from going away.

What should I do now, after I have good results from all my tests?

first of all, why are pinching your stomach? that will not help you. i dont understand why docs automatically go to mental issue when tests are initially clear. just because something hasnt been found yet does not mean it doesnt have a cause. can you describe the pain more? also, have you had a colonoscopy? i have read that an intestinal issue can transfer pain to stomach…
