I've just had my worst anxiety attack in years! I texted my girlfriend telling telling her what was going on and she got worried and called. When she called, I was short and probably sounded like a jerk. I was like this for 3) reasons:

1.) When I get really anxious or depressed, I have trouble speaking. Like the words just won't come out.
2) When she called I was about to feed my dog, and it was taking all of my willpower and focus to get a grip long enough to do that to the point I couldn't have my attention elsewhere.
3) I was barely holding my shit together, and didn't want to break down over the phone?

So that being said, I'm worried I've upset her. And honestly I just feel embarrassed, stupid, and burdensome.

Now the question is....what do I do? 
Apologize?
