What is bodhisattvahood in personal practice?

I've read a lot of english language scholarship on the mahayana, probably about 150 books thoroughly, with notes, though not always with very good notes. I wanted an opinion from a broadly Mahayana perspective, so here's my story. I was a sensitive youth, and had a number of religious like epiphanies while backpacking, before a more intense near visionary one with a basic Buddhist textbook. But this was truncated by a frank insanity: there is schizophrenia in my family. Anyway, my psychosis is doing a good job of shrivelling up with medication and therapy. But before all that, and before I clawed back some sense of Buddhism from my relatively committed reading habits, did I have an authentic religious (or Mahayana) moment? Or was it a religious delusion and / or escapism? How do I tell? I had taken a couple of Thai meditation classes, and since then have sat with a couple of zen groups, and attended a 7 day ch'an retreat. No-one took much interest, but then I am **near** broken now. I'm not asking for authentication from a web community, only: 1. What is bodhisattvahood in personal practice: is it OK to believe one (has or) did have that quality? 2. Does anyone *here* suppose they are a bodhisattva, without any group accreditation and with little engagement - outside their own personal striving / story / narrative? More esoteric or indeed polemical answers, are of course weclome.
