My best friend doesn’t understand anxiety

So I have a best friend who apparently to me, doesn’t understand anxiety which is a huge struggle of mine

We were driving about 2 hours away last night

-I was having anxiety that it was a long freeway and dark

-the unknown of not knowing the roads

-windy roads

-cliffs etc

I started to kinda panic mid way after a hour of driving like can you ask your friend how the roads are and he said yes they were windy but you’ll be okay

I wanted more information

-are there railings?

-how windy?

My friend ignored my request and I asked repeatedly, I said if I can’t find out I can’t go any father this is so hard for me

She kinda just ignored me and called her friend to talk

I said well can you have someone come pick you up because I don’t think I can go any farther (having a attack basically)

Instead of being supportive she starts to get mad and argue with me like I invited you I could have brought my own car no one is going to come get me

Anyway it just got bad.

She calls her friend and he actually calmed me down.

I had to continue to calm myself down and really get it together.

I ended up sticking it out but apparently my friend says she’s really bothered and doesn’t understand why I would say what I said, doesn’t get anxiety thought I was “dramatic” and had the audacity to say maybe you should get help.

Like does she not know that I have taken medicine taking counseling seen psychiatrists and I’m thankful for how far I’ve come but it was just like is this really my best friend ?

Any advise helps so I can try to see her side better or maybe try to educate her or talk to her about this situation because it kinda bothered me as well.
