Anxiety with chest pain and gastrointestinal issues

hi my names hassan im 16. lately for the last 2 months I've been having chest pain and anxiety. It started in late july i was out with my family and i had a sudden feeling of my heart getting squeezed and so later that day i went to the hospital they did an ECG and X ray and i was fine. From then on I've had anxiety especially since I've been perfectly fine besides a decently unhealthy life style. A few days later had chest pain ever since it happened went to the doctors and told me it could be bacause growing pain in my chest and acid reflux and found out that im most likely lactose intolerant. From then i took tums for 2 weeks and omeprazole to help. Prior to the event that i happened a few months before that i was having ear pain that my ENT cant find the cause of and so i took ibuprofen for a week or 2. The doctor thought that might be the reason. Fast foward a month later still chest pain anxiety slightly better i went out to get a desk and i had worrisome thoughts because i tend to worry and i was carrying as well so i had what i assume a panic attack that was very short. I had an extremely fast heartrate and felt weak. A week later i think i had another panic attack i was very worried had a bad feeling so i went to the hospital and they did another ECG took a urine sample and did a chem 8 blood test and i was perfectly healthy. After that my anxiety was starting to calm down a lot more lately with what happened they told me to breath if i feel anxious. A day later i went to the doctors about my ongoing chest pain and anxiety and he told me that my chest pain is probably because of anxiety and possible gastrointestinal problems and growing pain. He sent a referral and i got an appointment to go to a gastrointestinal office and get it checked tomorrow and i am waiting on a therapy office to look at my application. I have a sleep study scheduled for October 4th for possible sleep apnea to see about my ear pain that happened before. Also i have a physical coming up in a month. Right now i still have some anxiety that sometimes flares up when i feel some chest pain or a heart palpation i usually calm my self and tell myself its just my brain but i cant help but worry sometimes im wondering what the exact problem is? If i should get further evaluation about my heart and how has my chest pain started ever since that event took place to me it would make sense if i had gradual chest pain but not from an event 2 months ago and ever since I've been dealing with chest pain. I came here to sort of get some things off my mind to help with my anxiety and to maybe get some others opinions on what i should do.
