You don't give your age, sex, habits, family history, weight, etc.
The symptom "I always have a weird feeling in my chest" is emotional in origin.
But you also state that you are having "chest pain and pressure" but don't state where and when these symptoms occur. I don't know the origin of these symptoms. Also, when you eat something cold the esophagus is affected, not the heart.
Please be aware that I am unable to diagnose medical conditions online.
