Kendall... do what ya gotta do, but ya know how hard it is to quit. I know some days me Mum wants to go home early from our walks at the shops when I cough. I know it hurts her deeply (she lost a husband and a son to smoking) just as you have said it hurts you. But it's just hard to do. Then again, do what ya gotta do... it just might work or help, and that's a good thing.
