Everyone likes to act like being anxious about our lives is the enemy and should be avoided at all costs, but you do a great job at explaining the we should learn from it instead of avoiding it Gillian. We should learn from it and develop our selves from what it can show us. It can truly change us and help us grow into a more rounded person.
I know that if I avoided feeling the anxiety that I felt after my MS diagnosis I would just be a heavily medicated bump that sits here and does nothing. Instead I used it to try to become a writer and advocate for those that are mentally and chronically ill. We all have anxiety about our illnesses and lives if we are well.
We just have to admit it and learn to deal with what ever makes us anxious. Or learn that we cannot change it if it is something we cannot control. Those are regrettably things we have to make peace with and move on.
