i think i have pancreatitis or gastritis. do i have to go to the dr?

only been drinking every night for 2yrs. this happened to be once before when i went on a 2 week bender and i got better with not drinking without a doctor. been on another sort-of bender for a week and a half and since yesterday my upper stomach has been hurting a lot, i kept waking up last night in pain. it gets gets way worse on an empty stomach, or if i eat a lot. the biggest issue is i feel VERY short of breath, but went to urgent care yesterday my O2 was 97. also my heart rate was like 150. but urgent care was very bad and just told me to go to the er if i wanted to know what was wrong. i have the pain, shortness of breath, chest pressure/mild pain, nausea, loss of appetite, fast heart rate and palpitations, dizziness and near fainting (maybe dehydration tho) cold sweats (no fever) i haven’t drank since it started. should i go to another doctor, or will i be fine since its not severe? at its worst, the pain is like 7/10 not unbearable at all
