Ohhh, Candika
I wish I could think of one thing that would help the isolation, crying and pacing. The only thing I can say is that I really do understand. It just feeds on itself. The more you feel that way, the worse it gets. Round & round.
My t. made me promise to do one of my art projects even if my hands were shaking too bad to do it. I love to scrapbook & do beading. Better yet, there is a studio close to my house and I literally force myself to get in the car and go make a mosaic frame or a beaded necklace or something. I sit quietly, alone where I don't have to talk and I concentrate completely on what I am doing. It does help center me and it helps with the painful, physical part of anxiety.
Like I said, I wish I had something constructive to add. But please know that i am full of empathy for you right now.
