My dog. I deal with my anxiety by playing with, walking or training Toby.
Because of the stress of moving, and because of the stress of the location we're moving to, I have been really bad for anxiety lately. My husband had to wake me up one night because I had an anxiety attack in my sleep and was hitting my side table with my wrist and wheezing really hard. He woke me up because I wasn't even able to breathe. It was awful.
Toby is really the only thing that makes it manageable for me. I can't take anxiety meds because they mess with contraceptives and make them have a higher risk of failing. Since I've gotten pregnant on birth control before, I don't want to risk it at all. My doctor wanted to put me on anti-depressants too but I said no, Toby helps with that by getting me out of the house.
I haven't slept properly in days at this point.. I've been up since 3AM... :/ It's 12:02pm here.
Sorry I don't have more helpful advice, but I totally hear you!
