I think you should start looking for another job asap. Besides wanting to quit anyways, not missing any days for 6 months is totally impossible with your issues. I also loose every job I get due to chronic absenteeism, I usually last a year and a half. I recently filled out FMLA papers for a intermittent leave of 24 days as needed. Hopefully I'll make it to 2 years this time! Best of luck to you!
