Hello. Im Experiencing Sharp Chest Pain For A Month Now.

Hello. Im experiencing sharp chest pain for a month now. It started suddenly. Im having this sharp , burning pain everyday constantly , it doesnt stop. Im 20 yrs old. 2 years ago i was diagnosed with gerd and sliding hiatal hernia and she said that this pain comes from this. I was sent to the cardiologist who examined my heart with an ultrasound and it was all normal. My doctor said that im anxious and i went to the psychiatrist and she gave me meds. I stopped taking them a year ago. A month ago when this pain started i went to my doctor, she did an ecg , everything was normal and she gave me new meds for gerd because the old ones didnt work. Im taking them a month now but the pain just wont go away and its here 24/7 everyday and im really scared and dont know what to do. Thank you for your time and the answer.
