crunchy anxiety

hi all! not a child mom but a cat mom of 3, all of the crunchy groups i find have the word mom behind it but hoping yall can give me some advice anyway. i recently started going scrunchy about six months ago, but i have gotten some really bad anxiety from all this and am trying to go the full way with it. but as a 20 year old wife that works two jobs i can hardly find the time or the funds to do everything i need to do.

anyway, i work in a hospital lab right now and was wanting to further my education to keep working in the lab. my issue is my hospital requires year round flu vaccines. i got the covid vaccine when i was in high school, and got all the vaccines as a kid. i have constant anxiety over what i have already had done before i knew better, and am always worried a cancer diagnosis or something is gonna come out of the blue. just wondering everyone’s experience with similar anxieties and worries. i love my job and where i work, but im worried i wont be able to get over the required yearly flu shot for my dream job.
