Ok, so your OC is 90% Mary-Sue/Gary-Stew. Really? Are you being serious? If not, phew! You really had me going there! :) If you are, then..oh...this could be awkward. Your OC is an abomination, as sickeningly sweet as treacle tart dipped in honey and icing sugar and more frustrating than a sticky Rubik's Cube. You'd be best starting over, in all honesty. For everyone's sake. Your Mary-Sue/Gary-Stew is of the variety most commonly found in parodies, so if you genuinely created an OC that turned out like this, your idea of a realistic OC is laughable. Just leave it be, and stick to reading about Ed's latest tryst with Mustang or Al's obsession with all things small and furry.
Why not tell me what you got? All you have to do is press that little button, right there. Right down there. You know the one. All input is appreciated! :)
