Just checking... Actual agoraphobia... Fear of open spaces? Or trauma stuff? Isolating, control issues, anxiety/panic, stress & stressors, triggers, sensory overload, etc.?
Some of the treatment is the same, bit just like I'm not actually claustrophobic, I "just" don't like have my line of sight obscured/ being a sitting target/ captivity/ etc. (aka trauma stuff).... There's more to treating trauma stuff than phobia stuff. Not to say phobias aren't enourmously life affecting. But it's a single source thing, instead of a multi source thing, to oversimplify a smidge.
Some people honestly have both. I just want to make sure I know which you're talking about.

On the off chance I misplace this thread, if actual agoraphobia? Get your ears checked by a specialist. Come to find a staggering percentage of agoraphobics have chronic inner ear infections that screw up their ability to tell where they are in space. They can use familiar surroundings to compute where they are mentally, although it's exhausting, and any change to that environment can trigger massive symptom surge as their world literally tips on its axis as their brains are frantically trying to figure out "where" they are. One of the tells on this one is spiking anxiety any time you change elevation. Sitting to standing, for example, even in a familiar space. Or moving up/down stairs. Chronic inner ear infections need special medication to treat (and sometimes surgery if scar tissue has developed), as most are antibiotic resistant or specific to a few kinds of antibiotics that aren't given out for sore throats... or people wouldn't still have them after regular antibiotic usage to treat other infections! But it's a very very very easy FIX, in the space of a few weeks (Average is 72 hours post infection, the brain syncs up again with the world. Just like wearing glasses that make everything upside down turn right side up after about 3 days), if this is the source / as it's a conditioned phobia; rather than a psychological phobia, which generally takes months and years.
