You should never ignore pain, especially this severe. And never let anyone, no matter who they are, tell you that your pain isn't real or that something is all in your head. Ever. Do you hear me?
It sounds like you are having gallbladder attacks. The level of pain and the fact that eating can make it worse (usually fatty foods are the worst) all point to that. You need to see a doctor as soon as you can. If the pain is unbearable, go to the hospital and they can give you pain medication until the problem is resolved. Regardless, don't ignore it.
