I began getting hectic back pains and also a fair share of depression end of last year and beginning this year. I've always wanted to do taichichuan and I heard it helps with general illnesses like body pains and depression and stuff so I started giving it a go.
Its been a little over a month now and all my health issues disappeard. My back pain is gone(although my legs are stiff every once in a while from stance trainging

) and I haven't been depressed again since starting.
Maybe give Nanfeishen a pm, he's a taichi instructor in your area who might help you.
