I have started qi gong. why am i having problems with chi flow?

i started 6 mos ago. it seemed like i was doing well. more stress came into my life, and suddenly i became a statute when it came to chi flow. actually, i feel that doing qi gong made things worse. can anyone lend istance. i've stopped practicing, and i really did not want to do that, but i don't want to keep spending money for private lessons or seminars when it is just jamming me up. i know i need to relax, but what can i do to rid stress when something i thought would help doesn't............txs
