Hello everybody I am a 17 year old male and in need for help. So over 2 months ago I was feeling absolutely in top shape but then I wanted to do insanity. Now I didn't work out as much as the next guy but I never really had a problem with it and thought I was in good shape to be honest. But after the second day I had to quit because I was feeling short of breath and chest pain and I was worried obviously. And that Thursday I was rushed to the ER because I had my first panic attack. Scariest moment of my life I thought I was going to die!! But the docs gave me blood work, chest X-ray, and an EKG and everything checked out. So I went on my merry way but was still shooken up about it. So as the months past I started noticing more symptoms happening such as: chest tightness, short of breath, chest pains, couple headaches, palpitations and weird sensations happening in my chest like vibrating and grinding feeling in the center of my chest so to speak. And over those months I quit working out( mainly Cardio) and just kept thinking and thinking about it. Going on the Internet which freaked me out more and just straight up worried myself to death! Thinking that everyday was my last day and that I was going to die at some point during the day or night because of a heart problem. It was extremely emotional and after many " breakdowns" and visits to the nurse and counselor I set up an appointment with my doctor and they ordered me to have an echo and holter monitor for 24 hours and after that and the constant worry it came back 100% normal just as my parents and doctor said they would. And that gave me a big relief but now a week later I started to have bad thoughts of whether they missed something and all of my symptoms came back!! I am getting strange sensations in my chest such as vibration/ wheezing type feeling that takes my breathe away almost, palpitations, occasional tight Chest, and a feeling like my heart is being squeezed as it beats. It is all very debilitating and somedays I feel that I can't leave my own room because I'm afraid something bad will happen to me. I currently am seeing a therapist and sometimes talk to my counselor at school and that gives me some relief but once I'm on my own the symptoms come back and I start to worry alot that I will die. I haven't had a panic attack as bad as the one I had at the beginning but I have come close but have learned to control at least that. Please can someone help me? I don't know what to do with myself because I just want my old life back but I am trapped in this rut. Are these symptoms I'm experiencing normal for someone with anxiety and will they go away? Cuz I had all of that testing done and they all came out fine but even to this day I'm experiencing all of these symptoms in my chest and it's debilitating and frustrating and makes me feel like there is no hope for me. So i ask for you guys for any advice for dealing with this? Will I ever feel better? how long will it take before i feel better? almost everyday i think negative thoughts about my symptoms and death and this has just been the most stressful year of my entire life and i feel like i cant get through it. Thanks for those who may help or even know what I am going through and if you can offer any help please let me know. I visit my therapist every week and we talk about what goes through my mind when i think of death and what contributes to me having these bad thoughts and just getting to the deeper meaning of my anxiety. we just started on this so we havent gotten to far. i also have a follow up with my doc on the 2nd of May. Thank you for you time.
