Please help me, I need it :(

I'll try to make this short as possible: I graduated from LPN school back in 2012. I worked night shift a year and a half. I can't work night shift; it's bad for my health. I have Bipolar disorder type II (fall into depressions) for which I'm stable on my meds. I was going through an emotional difficulty right after that job until I got another job about 3 months later at a top research university. Unfortunately for 3 months, I had to put up with a preceptor who hated me, tried to turn everyone against me, and made me look like I wasn't doing my job.Trust me I was really good at my job.I was originally going to give 2 weeks' notice, but after I saw my supervisor blindly side with her without investigating facts, I arrived at an unhealthy level of emotional distress and had to leave the job right there and then.I could have reported her earlier but I had asked my father for advice and he said not to say anything.I now listen to myself more.After that, I went through more problems (relationships and deaths in the family) and couldn't look for work until almost a year later. I started to work at an outpatient surgery center.I was great at this job, too, with the exception of one problem: they were having me work 14 hours a day without 30 minutes of lunch to sit and eat. My body broke down from exhaustion and I left this one too without two weeks notice after 3 weeks. There was no physical way I could continue.I want to do nursing PT, but I have very large gaps that are difficult to explain and hide. 1)The general assumption is that I should never mention to a future employer that I left a job without two weeks notice.But what if the job I am applying to deals with the same I had dealt and done well with? 2)f I lie and deny having worked since then, can't they just refer to a background check and see that I *have* worked? Someone please help. None of this has been my fault. Life circumstances.
