Hello Sunny Side
Welcome to the forums and good on you for posting too!
Anxiety can be a crippling feeling with all that adrenaline pumping when we dont need it.
Two years after diagnosis is still recently diagnosed. The good news is with regular counseling the severity of the anxiety does reduce. I have had anxiety since I was 23 and I do understand what you are going through.
My anxiety was similar to yours...I had a doctor call it 'free floating' anxiety because there was no basis or apparent triggers for my anxiety.
As you are probably aware the worrying and thinking about the anxiety only 'feeds' it with more fear which will result in more anxiety. The regular counseling will help you rid yourself of the fears and the anticipation of having an anxiety attack. (I had weekly help for six months which helped a lot)
A psychiatrist told me to carry a couple of anti-anxiety meds with me in my wallet....Even without taking them they will be a plan B for you. Doing this also provides comfort as you have something to fall back on.
Sleep is a great support mechanism too. The better the sleep...the better you will cope the next day...
A good GP who has an interest in mental health is always a huge bonus...I still see mine for a tune up :-)
I hope there is something here that may help you Sunny. There are many super kind people on the forums that can be here for you. You are more than welcome to post back as many times as you wish!
My kindest thoughts for you
