I am wondering if an anxiety disorder might be what is plaging me. I have been feeling off for about 3 months now. I hurt myself while exercising, then I convinced myself that I had a blood clot. Thus having a series of anxiety attacks. Thankfully I haven't had ones of those for a while. I have been to the dr numerous times and most of my blood work came back clean. I was severely vit d deficient and my b 12 was low. So I am taking steps to raise that number. My newest symptoms is feeling like I am on fire at night. This is causing me to have insomnia. I do pretty good during the day, then bad at night. Took trazedone last night and it didn't help me sleep!! For those of you that suffer anxiety, do you have similar symptoms.
