No but seriously... think about it - if 12 (11) year old girls are at your level at similar bodyweights... where does that put you? It's not about me "shaming" you or whatever... the point is that you must acknowledge the fact that you're very weak and that is the only thing you should worry about.
No need in overanalyzing being weak. Just go out there and work and shut up. That includes myself.
If you have naturally strong legs and naturally weak back then the difference between your squat and your deadlift isn't going to be big. Obviously structural factors come into play as well.
