Another bad panic attack

It's getting where I can't go out to get groceries without a panic attack.  I wasn't there more than 30 minutes before it hit.  They don't have delivery services around here so I've no choice.  Of course, if I had anti-anxiety meds.. but my pdoc won't prescribe anything other than anti-depressants as they hate benzos... not that my insurance will cover the benzos.  Anti-depressants have NEVER worked well on me.  I mean, Lithium worked.. but do you think the doctors care enough to let me have a prescription.. of course not.  So, I have to suffer with the anxiety and panic attacks.
