Hi, I can relate to all of this too. Had anxiety for four years as a result of experiencing a bad panic attack out of the blue, from then on I feared going out in public or that I was going to lose my mind, and it spiralled downwards from there.
On a positive note, after all this time of not wanting to go on any medication because I developed a fear of going on anti anxiety meds, I gave in and got help and support.
I am now on Escitalopram and the difference it has made to my quality of life is amazing. I don't dwell on things too much, I am able to function normally without too much worry or panic and I have bags of energy. I also was very hyper vigilant so this medication changed all that and smoothed out the bumps.
If you can get a doctor who is very supportive and understanding, and a physiologist you bond with well, then that's just the start of a successful recipe for healing. I have been very lucky with all of this and have a very supportive network. It can get better.
