Yes there can be genuine reasons to be anxious, this is normal..
But with an anxious mind , sub-consciously your fear. Will choose a subject be it social anxiety, health, financial etc etc etc..
In these cases only finding calm will make your anxious thoughts diminish..
Talking is important for reassurance, medication and therapy helps, write a letter to yourself explaining how you feel and if possible be kind to yourself and learn to say " no"....
As your health comes first...
Remember your racing mind is making up stories and you are believing them....GBx
