It seems you are having a really hard time. I remember waiting a year for my diagnosis of crohn's disease and thinking I must be nuts the whole time.
I knew something was wrong but it took a LOT of tests to finally put a name to it.
I also stopped going out because the pain was bad and I was running to the bathroom ALL the time! Once I knew I had Crohn's it seemed easier to go out because I finally knew what was wrong and had a valid excuse for not feeling well.
I hope you get some answers soon!
