From what I can see...
Something untoward happened to her around 1996. Her earliest porn work seems to be from around 2003 (Aunt Judy's, Over30, etc). I would think that for the period of 1996-2003 she tried other lines of work that just did not pay enough to make a living. From 2003 to 2008-2009 she made regular porn and then had her car accident, which drained her reserves and screwed up her health. She got chunkier from then on. From 2010 on she made fewer porn appearances and moved fully into the escorting sector. Her homeless cycles begin about then - 2010, with postings in Humaniplex that have mostly been erased and with newer postings emerging in Twitter and FB. Interweaved in this time line is the occasional pining for a date or a male knight who will sweep her off her feet. If she has manic depression or some other condition it probably contributes to these cycles.

She may be heading for Canada to set up her pension and health care benefits while she convinces her younger sister to let her stay in one of the properties. If she has a kid or niece/nephew she may appeal to them.
