Hey so I've been diagnosed with a generalized anxiety disorder for a while (I also have ADHD, if that helps clarify some things maybe?) and over the last few years, I've started having these full body spasms as a reaction to worrying thoughts?  
It used to be just twitches of the neck or screwing my eyes shut really tight, but now, whenever I remember something embarrassing or have an invasive/ worrying thought, my whole body reacts. Now it's hard to stop myself from putting my forearms beside my head, twisting my neck and shutting my eyes (hopefully that was an okay visual). Often my body repeats the motion a few times for some reason- like I unconsciously must repeat it 3 times.  I've tried talking with my doctor, drawing blood to test for physical illnesses, and amping up my anxiety meds- I even participated in a psych study where they imaged my brain, and I was told all was well.  


I've never been diagnosed for a tic disorder, nor do I believe I have one. I just don't understand why this is happening to me. Some friends of mine with anxiety say they don't experience this, but I'm hoping I can find someone on here who understands what's happening to me to get some advice. Is this just an anxiety thing or something more? I'm sorry for sounding annoying, I'm just a bit paranoid.  


Thank you for reading :))
