Hi Wen, I came here looking for help dealing with my husbands depression/anxiety and your post could have been written about me. I'm reading up and stuff but he keeps worrying that I don't love him...
I don't know if I'll be much help...my daughter is the same age and has had the same problem. She has blown lunch while walking with me across a parking lot...very weird. She doesn't have low blood...
I'm pretty sure that they don't know how long the vaccine will last. I had the same thing happen to me although I was vaccinated much before you. Within a year I showed no detectable antibodies....
