Hi Machelle.. I am sorry to hear that your anxiety is so bad. I don't have this problem regularly, I just have it when I am under an infinite amount of stress, which I have also had for the past month and a half.
In many respects, I think that you have already answered your own question. Finding a physical project keeps your mind away from the "smaller" details, yet allows you to work off some steam. Do you have a cellar you can clean or projects around the house (or apartment) that you could do? Or I am not sure where you are from, but it is very cold where I am (US - New England) and I just started planting seeds for flowers (they will be for containers)..for me it feels so good to see them when they start popping out of the soil. ...Or even just smelling the freshly watered soil gives me hope of spring coming soon.
These are just a few ideas, but it sounds like you are already on the right track. Keep in touch and let us know if these are ideas that you might consider doing.
When we have company over I talk to my hubby ahead of time and ask him to take care of certain duties that I am uncomfortable with such as pouring coffee less my shaking hands pour the coffee in their lap.
Also when I am trying to get dinner on the table I ask him to be sure to seat everyone and then help me dish up, he can put the platters of food on the table.
If my daughter is here I just ask her to be my kitchen help and she does. We have a small house so entertaining is tough. Everyone wants to stand around in the kitchen and dining area. No one will go down stairs to the family room.
My favorite kind of entertaining is to order Pizza or take people out for lunch.
Your not alone with your anxiety. Hugs to you.Kitt
