i might of developed health anxiety a few weeks ago, after trying out the gym for a week i had an episode or something where my heart was hurting a bit and the i nearly fainted, after that i just kept gettin dizzy every time i tried to workout without the heart pain, i went to the er they checked my blood, heart, chest. i was fine it eased my anxiety a bit but its back, im at home i feel like i have shortness of breath, random 1 seconds aches from time to time, and im terribly tired even after i slept for 8 hours like i have no energy, my head feels foggy. Im really tired of it and i keep thinking something is wrong with me. i do have vitamin d deficiency but im not sure if thats the only thing affecting me right now.
