Scared to leave the house

[anxietyhelpplease]

For the past few weeks/months I'm becoming increasingly anxious. My jaw constantly feels clenched and like it's out of control almost - I can't explain it. My head is spinning.

It seems to be worse whenever I am out of the house. Even at others peoples houses, I'm scared I pass out or come across as weird so I have just been in my house for a month or two.

I'm absolutely terrified but scared of becoming agorophobic, how do I stop this?

Does anyone else understand what I mean by anxiety and the strange jaw feeling?
