Hello, I just need someone to hear me out. Please, I'm not trying to scare anyone with this. I'm very anxious right now.

I got my first dose of the Pfizer on the 19th in the morning. I am surrounded by people who express all sorts of opinions of this vaccine. I'm all for science, and understand it is not perfect and there are always risks. I lost 3 family members due to the pandemic and some had similar conditions I do... this is why I ultimately got it. I'm now being faced with taunting information on how I should've waited, what this might cause later on, if I'll be able to have children, if I'll develop serious or life-altering changes years on because of it, etc. I listen to both sides and can't help but feel extremely stressed out over this. I'm not sure if I can safety take my regular medication as there isn't enough data and time to go on about this. It feels weird and eerie to feel like this.
My have two symptoms that have persisted since I got the shot: a lingering jitteriness (it's better today), a bit of insomnia (slept okay today) and a tightness similar to when you get GERD (esophagus feels tight, heavy chest) -- But I can breathe fine and otherwise feel fine. 
I have a million questions and am mostly worried that I made a mistake. All of my family (except one) has been fully or partially vaccinated, but as of late it has been the cause of a strange dread/anxiety, etc.

I just needed to say this to someone. I'm mentally exhausted.
