I can relate to a lot of what you're experiencing. My anxiety triggers are different, like I react like you to things like lightning/thunder or if someone comes up behind me and touches me. I almost literally jump out of my skin.
I really relate to the sudden anger and I have been known to punch a wall or throw things. I've never hurt anyone, but sometimes I worry about it.
When I sought treatment for these problems, I was diagnosed with PTSD. I'm not saying that's what's causing your symptoms, because I'm not a doctor and not qualified to diagnose anyone, but I definitely think you should find a therapist and a psychiatrist you feel comfortable with and tell them what you are sharing here. I have found that a combination of therapy and meds to be a Godsend and while I still have bad days sometimes, I am much better than I used to be.
Keep us posted on what you decide to do and your progress. It's always great to hear from new members.
