@Icantbebrave I completely understand your anxiety.
I'm group 6. Two weeks ago, totally out of the blue, I got a text saying to go and make an appointment. I was the first one in a large group of carers (all group 6) to be called up. I am very pro-vax in general and not scared of needles in the slightest.
I spent 48 hours in a terrible state. Convinced myself I was going to have an allergic reaction and die. Kept looking at the DC and wondering if I'd see them again. At the same time, I was completely aware of how irrational I was being. I can't even explain it. I don't believe the conspiracy theories and I spoke to my DB who has a pHD in this field and he reassured me about safety, procedures etc, and explained that actually this tech has been around longer than the public realises. I don't know why I was so worked up or anxious.
On the morning of the jab, I was in floods of tears. Made myself go and have it because I don't want to catch COVID and leave two disabled children without a mum.
And actually, I feel bloody amazing that I had it. So relieved to have the protection and just so grateful that I was given the chance to have it.
What helped me a bit is if you get some mild cold/flu type symptoms after the vaccine is to remind yourself that you're not actually ill. You will experience this for a very short time only, and you will be completely fine again in a day or so. Also, I found it helpful to remind myself that the side effects I noticed were actually the result of my immune system jumping into action. It isn't a virus or an infection, but a result of my body diverting attention elsewhere to kick ass. Thinking of the side effects as proof of how strong and fit my body was in fighting off what it perceived as an intruder really eliminated the anxiety.
That might not work for you, but consciously shifting my mindset really helped a lot. I have literally zero concerns about having a second dose now.
And yes, I have health anxiety too. I panic over new meds etc. So I totally understand it's horrible. I've had counselling and am still working on myself.
Remember: the choice is yours. You decide. I was more scared of getting COVID and dying. I thought to myself, if I got COVID and ended up in hospital, I would absolutely kick myself for not taking the opportunity to get protected. I've got some health issues of my own, so for me, the idea of COVID really scares me. Again, understanding that you are in control, you have all the power to make the decision that's right for you. For me, understanding that helped me gather my mental resources to go and have the vaccine.
