Baptized previously in a radically different denomination (Mormon Church).

I posted previously concerning my interest in joining the Episcopal Church. At the moment I am curious as to how my previous baptism from a church I left (the Mormon church) would exclude me from potentially being baptized again. Not that I feel it's an absolute necessity, but I would certainly appreciate the symbolic nature of it. In an instructional guide I was reading it stated that the Episcopal Church respects any previous baptism, however the Mormon faith is radically different from most Christian denominations. I'm wondering if I should just let it rest and allow myself to feel that my baptism in that faith is valid enough. It's difficult because I have so much trauma from that church, including abuse from clergy, that it's challenging to value my baptism there.
