As far as your anxiety is concerned, you might like to learn how to use Cognitive Behavioural Therapy (CBT) methods, ideally with assistance from a mental health professional.

I used to go to a weekly therapy group for people with mood disorders and now use CBT methods to stay in remission from MDD.

A woman there, initially with severe GAD, refers to CBT as her "toolkit". By that she means that she now knows the right CBT tool to select and use when she is experiencing anxiety.
