Depression can only be cured by finding a sense of purpose or at least self-worth. Usually people have to define that for themselves.

Anxiety, that can be compensated for by acceptance (in the sense of the Tao or Zen). It can relapse in situations where your senses are overwhelmed, but then it becomes something to be managed rather than 'oh well this is the way I am'.

step out of your limitations no matter how much it hurts and you break free of depression. if that is not possible relaxation is the only relieving act. depression is consequence of experiencing limitation.
