This shit is ruining my whole life

I just want to live normally like a regular young person, I want to have fun and i don’t want to worry about shit’like this anymore. I used to love food so much and now I am scared of it because everything triggers me and I have to lay down for at least 30min after every meal because of my stomach pain, this makes working, hanging out with friends etc… so hard. I told my GI abt it and all he had to said was « the stomach is the second brain of the body, stop stressing and everything will go away » because yeah women are just sooo emotional and everything is stress related. I just booked an appointment with another gastroenterologist (my old one also told me that women were too emotional lol) and I am hoping for the best because my symptoms are now out of control, I look pregnant all the time and I’m in so much pain.
