22 year old male. I just got he flu shot today that was required for a new job I just started. I haven't had the flu shot in 10-15 years and I'm having anxiety that the flu shot will make my immune system weaker and could also potentially cause some sort of cancer like leukemia or something bad? I've read that the flu shot is not as what it turns out to actually be. I'm also worried that the government uses it as a population control and puts certain things in it that can cause cancer or other diseases. Am I overreacting? Im not a conspiracy theorist guy at all but I may have went off the deep end on google. I honestly am sick to my stomach that I got the flu shot today and feel hopeless.
