New issue my doctor doesn't seem to care about

I've struggled with PTSD eating disorders most of my life. Long story but it has getting better. But for the past few weeks I get this horrible pain and pressure when ever I eat. It gets so bad I have to make myself throw up. I had an appointment with a doctor, after my er visit over the weekend. Not my normal one he was out sick, this doctor had no understanding of my tourettes, he pretty much blew me off saying I should take some heartburn pills and drink more water. This is not heartburn. I don't know what it is but I haven't had pain like this before. I've barely eaten anything in a week. I can't keep going like this.
