Potentially Hypochondria?

[BorealisImperator]

Hello Everyone, I am a 19 year old male, overweight, with GERD but no other health problems. My bout with what I think might be hypochondria started in about October last year when I got a random heart palpitation, which made me more conscious of my heart and heart disease. It wasn't that bad at that point, but it was present. On an unrelated incident in mid-October I took Tylenol cold and sinus for a cold I had, and it made me dizzy and sent my heart rate through the roof. I panicked and went to the emergency room via ambulance, and was told it was a bad reaction to the medication I had taken. I was given an ECG which came back perfectly. In early November I began feeling weird, fuzzy headed and off. I wasn't too worried at the time, until I started getting a headache on the left side of my head. I then became convinced that I had Brain tumours and was going to die. I went to the doctors office and found out that it was Sinus congestion, which I still currently have and am taking Nasonex spray and using a neti pot for. Everything was calm for a while, but I was still constantly conscious and worried about having a heart attack or some form of cancer. In late December just before Christmas I experienced another Heart Palpitation except this time I began focusing on breathing, and I developed an obsession with my breathing. Since then I will pay attention to my breathing and I must control it otherwise I feel like I am going to stop breathing. Since then I have been extremely worried about having a heart attack, despite constant reassurances I am not having one from family members. Any little pain in or around my chest area will set me off and make me scared, and I am constantly checking my pulse and my body for tumours and such. I recently bought a Rescue Remedy spray for anxiety and that helps take the edge off a bit but the worry is still there. I have a doctors appointment coming up soon where I will be discussing all this, what should I expect and where can I go from here? Can I help myself at home?
