Hi there Jarred and thanks for your post!
I see that Sophie_M has suggested some links to explore with coping strategies, and Petal22 has also responded.
I feel for you as these symptoms must be horrible to experience so constantly. You have taken an encouraging first step by booking in some professional advice. Of course I am not at all qualified to give you advice, just a couple of suggestions as like everyone on this forum, I'd like to help if possible.
It seems you brain might well be working overtime with sending stress hormones to the rest of your body. I wonder what it is that might be causing your unease or uncertainty?
If you are able to perhaps come close to identifying what it is and share it with us, we may be able to help a little bit. It matters not how trivial any issue may seem, if it bothers you it is able to be discussed.
When I was hit by panic feelings over the years I found a song that really helped me. Its the old Doris Day song called 'Ke Sera Sera, what ever will be, will be, the future's not ours to see etc'. By using the words for the chorus and singing them to myself over and over like a kind of mantra, it seemed to work like meditation.
I always feel calmer after this song as it sticks in my brain and I hum it for ages.
We can't really control the future, but can prepare better for whatever might happen by relaxing into it and taking an 'If it happens, it happens' type of approach.
After all, what's the worst that can happen? life goes on and there is every chance you will look back on this in time to come and see it at a learning experience, a speed bump that set you on a better course to self belief.
I am very happy to discuss at any time Jarred28, just get back to us if you want to.
Hope this has helped a little bit.
All the very best, The Bro
