Hi Blackberry,
I am sorry you feel that you are feeling anxious at the moment.
Reading through your post I can completely understand where your anxiety comes from and how difficult it is for you to try and and deal with this. I also suffer with fatigue and muscle pain/twitching and when I am anxious and I also spend hours googling various disorders. It is a very difficult cycle to break.
I am only going from personal experience but do you find that when a positive thing happens in your life (you are recently married) you feel that somehow something bad is bound to happen because ''that's life"!. I know this is something that I think which perhaps underlies my anxiety issues.
I am currently trying to combat my anxiety by focusing on positive things in my life and most importantly I rarely google any symptoms. I have to keep in mind that I can either live life or I can spend my days worrying about things that may never happen.
It is difficult to let go of anxiety but it is not impossible as you have already proven to yourself once.
Positivity is anxieties arch nemesis!
