There is only one cure — cure — for anxiety.
Coping mechanisms are many. Relationships. Money. Substances. Talking. Spiritual practices. Various "doing" strategies.
Anxiety ends where knowledge and knowing begins.
Anxiety is distrust of an uncertain future. Such distrust is rooted in belief of an independent "I" or "me" on its own.
Knowledge says: come what may, I am OK.
I am OK. Ever and in all ways.
Knowing this vs. understanding this—this is the end of anxiety, once and for all.
