It's great that you got a new job! Congrats
Myself, I couldn't keep a job for more than 6 months... most were about a month. 99% of my jobs were in retail. In the beginning I would be all into the job... so focused, doing more than my job description and then wham! I just couldn't keep going in, I'd realize (whether real or not) that I was being taken advantage of, start calling in, or just not showing up all together.
Course I have more than just BPD... so I don't know what part of my illness play what part in this issue.
Did I answer your question?
