There IS someone out there for everyone. A lid for every pot.
Many heavy men will find a heavy woman attractive (and vice versa). Also, there are many people of varied backgrounds out there; I know of a Chassidishe girl (Emunas Yisroel) who married a black ger. I know of many unlikely shidduch stories like this, as well. In my case, I am the BT/giyur le chumra child of a father who was raised very frum, in the Brooklyn Sephardi community, and went off as a young adult, and I am involved with a girl who is a BT whose grandparents are frum and whose father went off after being raised in the Breuer’s kehilla. (In both our cases, we beat the odds, returned to halakhic Judaism, and prevented who knows how many generations of assimilation away from klal yisrael?)
My point is that an open approach will go a long way in shidduchim.
