I get like that sometimes too. Try picking out places where you can go that make you feel safe. Even if you just drive around, but don't get out of the car. Eventually, you can venture out further. Try to go outside to pick up your mail. Or perhaps go to a library. You don't have to talk to anyone, just sit and read for a while. The more you try to go out the better your anxiety should feel. Best of luck to you.
