M 26, vaper. everyday i feel tired and out of breath from the moment i wake up. constant fear of sudden cardiac death or respiratory failure. palpitations and shortness of breath whenever i feel off and really obsess over my heartbeats and breathing?

You need to have your shortness of breath evaluated to be sure you do not have any serious issue. You also need to stop vaping. Vaping can lead to lung issues that result in damage to the lungs. If you need help quitting, your doctor can help. Good luck to you!

Would suggest starting with quitting vaping and increasing gradually physical activities. If symptoms persist seeing your doc would be best.
