Not sure what you mean by "fight" and "struggle", but I think the key word worth adopting is "accept". I am saying this because this is what my therapist advises, but it's really hard to go along with acceptance when you are in the thick of it.
He says that if I resign myself to this, it will help. Constant focus on the pain, the anguish and suffering does us no good at all. Again, easier said than done, but I feel it is good advice.
I have avoided anti-depressants for 3 years, but am going on them in a few days.
How much are you able to escape from thinking about anxiety in your life? Are you able to get out on socials etc. to distract?
