Anxiety Support Group
Anxiety is a physical condition marked by intense and persistent feelings of distress, fear, angst or dread. General anxiety caused by routine day-to-day stresses usually passes quickly and is experienced by almost everyone at one time or another. However, such feelings that linger over time and are very difficult to cope with, and which lack a clear cause, may indicate...

I definitely have the same type of anxiety symptoms you talked about. Also like you said, some days are great, and others are so awful you wonder how you're ever going to have a great day again.
The "intrusive thoughts" you mentioned, I struggle with all the time. Its as if my brain knows what scares me the worst and then sits there and replays the scary thoughts over and over. Like you visualize choking or falling down the stairs, I do the same thing only I fear I could be chopping vegetables and then stab myself without meaning to. They thoughts get more violent and so incredibly scary because I know that I would never ever consciously hurt myself.
I get so tired of hearing to "deep breath" and "this too shall pass" but deep breathing really does calm me down. I inhale for 7, hold for 3, exhale for 12 and repeat as many times as I feel that it takes to make my heart stop pounding. Seeing a counselor does help, they are well versed in all of these things and want to make us feel better.
Distraction seems to work occasionally like you said. Last night I was feeling very anxious so I literally put on a cheesy Hallmark Christmas movie, pulled up a crossword puzzle on my computer and diffused the "peace and calming" essential oil in the room.
Rather than waiting for your husband to get home to eat, would you be able to eat applesauce, pudding...etc. something that wouldn't require chewing so you knew for a fact you wouldn't choke? When I was explaining my anxiety to my aunt the other day, she told me she used to be the same way about food. That she'd convince herself she was going to choke that she would only eat baby food for months. But guess, what, she got better.
Sorry for the novel, you are NOT alone. Your "symptoms" are very similar to mine. What I keep trying to tell myself is, "hey, Christmas is next week, do you think we could shelf the anxiety at least until Christmas is over so we can enjoy this time?" Maybe that'll work for you too. Merry Christmas!
