MBGibs, there's a horrible prejudice towards SAHM (stay-at-home-mothers), young mothers/parents, moms over 40, and even older women "interrupting" their careers to have their children. As if making new human beings and growing new persons was less important, magic, marvelous, demanding, responsible then chasing a career. as if it was something EASY. you know, someone's "just" a SAHM or so...
...the fact is, doing your A levels, passing your exams, partying your ass off, being the most popular girl in the school... is all a mere bullshit compared to having a baby.
you're 100 times braver then any other kid in that school, just for a mere fact of putting your foot in there while having a baby, and you should be aware of that. and infinitely more responsible then any of them, too. if i were you, i'd wear a printed t-shirt over my bump saying: "are you strong enough to accept this kind of responsibility?" or "can you give this kind of love?" and let them read it when they stare. (ok, might be a bit of an extreme move, but you get the point: just don't go hiding in your car!)
there's always gonna be people with prejudices, no matter what u do in your life. but there's always gonna be people who are going to understand you, love you and support you.
if you break the silence and treat them as your equals, they will treat you back the same.
and trust me, 99.99% of those kids in the corridors are insecure, self-conscious and are struggling with their own inner doubts, weaknesses and insecurity. they are all way more vulnerable then what they seem. the only difference is that your vulnerability is more evident and exposed then theirs.
some may mask it with aggression, over-confident attitude, brilliant marks in order impress everybody (and by that convince themselves they're worth of something)... some may bully others, or stare at your bump and gossip behind your back and point fingers... the truth is, people who truly love themselves and accept themselves are very few. and those are the last to point a finger to someone who's different for some reason.
so chin up... and go sit and eat where all students do. even if you sit alone, you are still giving a chance to someone to approach you.
