Young single moms?

Am I the only one who feels judged just for being a young single mom? Yeah, I didnt plan my baby, yeah I'm only 19. But I'm proud of myself for still taking on the huge task of motherhood, when I could have opted out. My baby is healthy and I do my best. Yet I feel like I'm never good enough for other people. A 30yr mom whose married can do something and everyone's fine with it, but the minute I do it, suddenly I'm a bad mom. Why am I any less legit than another mom?
