Just as like, a general note: if you are leaving a messianic background (whether you chose it yourself or not) in order to seek a true connection to Judaism, most rabbis and Jewish communities are going to be thrilled, actually. (And if they're not, they're in the wrong and they should be happy to have you.)

The thing is that while Judaism doesn't proselytize, we DO want klal Yisrael (the whole People Israel) to be Jewish and doing Jewish instead of avodah zarah (foreign worship, idolatry.) Some take that in an unfortunately fundamentalist direction, but most just want to have a strong Jewish community free from predatory missionaries and hucksters and pressure to assimilate.
