Smoking

This is KAT.  I feel really guilty.  We started doing a volunteer training thing and there were people there who smoked.  A couple of times a mooched a cigarette off of people and it got me started again.  I bought a pack.  I have vowed that when that pack is gone I will not buy another.  This is a temporary thing.  I am hoping and praying that there will be no negative consequences to this...health wise.  I keep getting signs that I should stop but, I really want to finish this pack otherwise it will bother me that I didn't.  It makes no sense.I feel like such a failure.
