Hello Shr08,
What you're experiencing is something I used to struggle with a lot. I'd say for a solid few years and it tore me apart. I'd always tell people "I can't deal with myself" for that very reason. The constant worrying about everything. It was so exhausting.
My understanding is that this is also very common and I'm gonna let you know how I solved this issue in particular. It does take some effort, but I promise it'll help. The main thing you have to train your brain to do is have no resilience to your thoughts, accept and allow your anxious thoughts and feelings and they'll have no power over you.
I recommend you check out Therapy In A Nutshell's YouTube channel and have a look at her anxiety related videos, heaps of valuable anxiety tools and coping mechanisms, as well as research how you feel as more understanding will help you remain calm. I also recommend Dare, it's a book, an audiobook and it has an app too. It'll teach you how not to fear your anxiety.
Everything you're feeling is just a sensation caused by your nervous system which caused your body to produce an excess amount of adrenaline and put you in a state of fight or flight. I'm currently also worried of panic attacks, I've not had one for awhile but the thought of them re-occuring makes it hard to get out of my comfort zone, so I understand what it's like to have them and the effect it can have on you.
I feel as though magnesium & calcium tablets have also helped, so look into the best one of those for anxiety if that's of interest to you as well.
Lastly, make sure to check in with your GP, you could have a thyroid problem that's spiking your anxiousness or they could prescribe some other medications that won't make you feel bad.
I hope this helps 🙂
