Question: I had an attack of not being able to breath when it happened i was in the shower i felt like i was going to pass out and was really weak i also had a tight squeezing feeling in my chest. Since then I've had other symptoms but i was healthy before the attack other then the occasional palpation now I'm short of breath doing the lest of things weak dizzy when standing lightheaded and i stumble around a lot like i cant keep my balance. I have a tight feeling in my chest like its full of water and i gained about 5 pounds in roughly 2 weeks when my weight was stable i have gained any for the last few days. I have palpations more often now my heart rate goes up and down and when i listened to it sometimes it sounded like it had an echo i have had light chest pains but not all the time and also nausea. I got really light headed and felt like i was going to vomit and pass out i had to take out the trash and by the time i hot back from the short walk i could bearly breath. These things rarely happen together only the dizzness lightheaded XXXXXXX and stumbleing. I have always had some trouble focusing but its gotten a lot worse now i cant keep my days stright and forget whaf im doing easily. I dont seem to be going to the bathroom as much now i have only been going about 4 times a day it used to be more and i dont have as much of an appetite i have only been eating 2 times s day now and i eat about 3 or 4 before. I am over weight but i dont think thats whats causing the breathless XXXXXXX i had no symptoms till the attack. My weight is now 180 and i am around 4-7 feet tall.
Please tell me what this could be i really dont want to go to the doctors unless i have to cause there going to want to stick me and i have a phobia of needles

Iv havent had any test done before i had thought the palpations were normal they only happened every once in a while
