Greetings @sickman123. In your specific situation, we are looking at either panic attacks or hypochondria. The symptoms you described—shortness of breath, excessive sweating, a sense of impending doom, arrhythmia, or a racing heart—are textbook signs of panic attacks that often stem from past trauma, whether it occurred during childhood or later in life. On the other hand, if your doctors insist your tests are perfectly clear yet you still feel unwell, then you might be imagining it all... which points toward hypochondria, characterized by an intense fear of illness and perceiving ailments that simply don't exist. Look at it this way: nobody here has labeled you as sick, and I certainly don't view you as ill, yet when you signed up for this forum, you chose the username SickMan... implying that your illness has become such a core part of your identity that it defines you. Isn't that a bit strange? It sounds incredible, but it's true: if you suffer from hypochondria, you can even feel pain in a tooth that was pulled ten years ago! Hypochondria can also be closely linked to a craving for attention. There are many people who feel terribly lonely and begin to manifest illnesses just to draw their family closer. In any case, I believe your issue is psychological in nature... something you will have to uncover yourself by reflecting on any unpleasant events that may have triggered this state. It would also be wise to talk with your family to see if anyone else in your lineage has dealt with similar issues. Initially, I would strongly recommend that you immediately stop taking any and all pills if you feel they aren't helping... and instead focus on working on yourself, building your self-confidence, and organizing your lifestyle. Start making progress there first! Go to some baseball games and, regardless of how you feel about profanity, "vent" your frustrations at the umpire or the players as much as you need to... it's a great way to release stress! Surround yourself with optimists and stay far away from pessimists. When you go for a jog, listen to relaxing music on your phone or run with a friend while cracking jokes. Get out into nature... and finally, you might try an old folk remedy sometimes used in rural parts of the country where I grew up, involving pouring molten lead into water. This isn't about the medicinal properties of lead or the water, but rather the sheer shock of the experience... the sudden fright can reset a stressed brain, overriding old fears and clearing the mental slate through pure adrenaline. Good luck!
