Have you and your boyfriend been together long-term? Even if you have, sometimes our obsessiveness to our bodies (even when something real is going on) can wear on them. I do understand why they get frustrated, even if their comments like "can't you just forget about your arm??" are completely naive to me. How could I possibly forget?
When did your uncle pass away? The sooner you deal with it (as long as you're ready to), the sooner it'll get under control. I didn't deal with my anxiety after my dad died right away, and the therapist I eventually saw said that likely made it a little harder to manage.
I think you're right about the flood gates opening up - when I had the first bout of PTSD, I was in a situation where I couldn't deal at all. I did swallow all my emotions.
As far as the physical, I have problems with shoulders, arms & hands. These do appear to be real, semi-diagnosed problems - doc's still trying to figure some things out. But, in the past year I've had a few other issues as well. I've had burning in my chest before, likely stress-related acid reflux. The reflux really screws with the way your heart feels. Mine used to pound in my throat until I thought it would come out of my mouth. Stress does a lot of things to the digestive system, not to mention your heart rate in general.
Hi & welcome to a fellow newbie. Heart palpitations are such a classic anxiety symptom. As a demonstration, my doctor once told me to start thinking about my breathing and my heart rate while I was sitting in her office. All of a sudden, my breath was heavy and my heart was pounding. Just paying attention to it made me feel that way!
It's great that your husband was so supportive from the get go. I always feel bad because when I met my fiance, I wasn't anxious and my physical symptoms hadn't yet arisen. About nine months in, my dad died, and all of a sudden, my then-boyfriend/now-fiance was dealing with a grieving, anxious mess of a woman.
