Has anyone here had a stomach ulcer before? What does it feel

Guess I should give some back story.

It was about 2 and a half months ago and I had just come home from work. I had eaten like a pig and had a ton of coffee. Then I smoked a blunt. I had smoked weed regularly but this wasn't right. Next thing you know it felt like a thousand knives were digging into my chest. It was awful and I couldn't sleep. I induced vomiting. I took peptobismol, tums, and even milk of magnesia later and got everything out of my stomach. It was as if my heart were beating faster. Maybe I was having a panic attack. So I don't smoke anymore and I don't drink coffee.

Fast forward to now and well whenever I eat the things I like it's like someone is lighting a torch in my chest. I just burp and fart continuously until I go to sleep. My chest is so damn tight and burping relieves things but only for so long. This is why I'm gonna go see a doctor.
