Just know that you are not alone and we are here to support you!
I do always recommend following up with your doctor just to get things checked out because that will give you peace of mind when your test come out OK. Keep in mind that any symptoms that are related to anxiety cannot hurt you. They feel weird and can be scary sometimes but that is all they can do.
there are a couple things that could really help you as they did me. If there's anyway you can get a copy of a book called mindfulness that teaches you how to manage your anxiety and it's definitely worth reading.
Another thing is YouTube has so many great audio meditations for anxiety, depression, sleeping well etc. I use my earbuds and lie down to listen a couple times a day. It completely calms down my whole mind and body and they teach you how to separate negative thoughts from yourself etc. my symptoms definitely die down or go away.
Anxiety starts in the brain and the only way to get rid of symptoms is to calm down your brain. These meditations are great for that. just do a search for meditation for anxiety or panic attack if that's what you're having. The more you do these the more your brain will believe that everything is OK.
it's it's important also when you are having negative thoughts or feeling anxious, to do slow long deep breathing where you see your belly rise.. When you blow out through your mouth it should be like you're blowing out a candle. You inhale through your nose. Do this several times. Focusing on your breathing takes you back to the present moment so you're not thinking about 100 different anxious things.
also, try not to react with anxiety when you get the symptoms because that will create more anxiety. That book explains all of this.
I have had the exact symptoms you have including the ringing head, legs hurting and many more. Remember those cannot hurt you.
also I had to learn to not take life so seriously. I had to learn to laugh and smile more even one having symptoms. Instead of becoming fearful with symptoms, I now tell myself that I can handle this, everything will be OK and this will pass. Then I go about my life with or without symptoms. If I feel really anxious I will listen once more to the audio meditations
. You have to be relentless and fight for yourself! Don't give into the fear! Stay as calm as possible.
Also I spoke with a counselor who really helped me a lot. This is hard to overcome alone and it always feels good to talk to someone else in person who has the tools to help you.
just to let you know, my really bad anxiety started in my 20s and I am now in my 50s and I'm still here! I had every symptom from A-to-Z and like I said they are annoying but they can't hurt you. I hardly get them anymore because I have learned how to manage them. You can do this!
