Held back by random anxiety

[MRW]

This is really hard for me to explain as I barely understand it myself.
I have generally always been the most confident, exuberant and outgoing person. I loved travelling and really didn't bat an eye about anything..
I am not saying this to be boastful, I am just giving context.
I've been physically assaulted on the street in my younger years twice.. once by bullies where I was punched in the face, and another a few years later on a totally different occasion where us was pushed to the ground and had my face kicked in for my mobile phone!
Not that this should make any difference at all but I was a private school girl who was shy so I guess I was a target in a way.
Typing it down it sounds awful.. which it obviously was.
Anyway, after all that, I just got on with my life and really never thought anything about it.
Then, one day I was on the underground and there was a fault on the track and we were stuck under there for over 30 minutes and i suddenly had a panic attack.
I have never had one before ever. Not even after the random things that had happened to me before.
Now, I feel so stuck. So afraid of travel and it's really holding be back as this has never been an issue for me before.
I have done lots of different methods of therapy and none of them help.
What to do now?
I really don't want this to keep holding me back as I was such a trooper before and I want my life back!

How old are you ? Peri menopause gives anxiety.
Can you ask the GP for something, like propranolol, for the times you need it ?

Thank you for you your reply. I'm mid 30

I was also going to suggest propranolol alongside therapy.
The meds might calm you enough in the moment to help you use the techniques from therapy.
Have you tried step by step. eg Go to the top of the tube stairs, do your breathing / grounding exercises until you feel calm. Repeat a few times. Next time go down the stairs to the concourse, do your breathing / grounding. Repeat. Then onto the platform, etc?

Also, has your therapy addressed the underlying reasons/trauma, or just tried to resolve in the now?

@TeenDivided I have done those steps and I'm doing so much better. I can get on tubes and trains if they're not too busy. I'm now terrified of getting on a plane, as that's really a trap. When I fly it's usually long haul to California or Florida. It never bothered me before but now the thought of it makes me sick.
With the last panic attack they gave me a sedative which really did nothing!
I will ask the doctor for propranolol and see how that goes. Thank you 😊

Mid 30 is exactly when my anxiety ramped up significantly too . I put it down to hormones

Oh no! That's really depressing 🙁
