I've accepted myself, how to come out? be accepted by others?

[Robzxox]

So, i've accepted myself being Bisexual, more lesbian than straight though.
I would like to be open and be able to walk around with friends in town and be like 'oh, she's fit!' like you do to guys!
my problem is, i only have one friend in college who i hang out with... she's really judgmental and a bully to others, i hate this about her. Do i try make new friends then slowly come out?
I go to a farm where i have friends, all different ages, we only hang around at the farm, should i tell them? i think they'll accept me no matter what, i've know them over 5years! and one girl has already gay friends!
also, my mam, she's not the best person to talk to, should i come out to others first or her? i feel most uncomfortable telling her than anyone!
i had a friend last year who's gay, but we don't see each other anymore, he's pretty bitchy, but we text very frequently, should i tell him with him being gay?
everyone i know who is gay, has always acted/had the camp look so people have always assumed they're gay/named them so theres wasn't as hard to come out, i've never been asked or assumed i'm gay/bi, i feel this makes it harder! i'm not butch nor femme, i've had my hair cut shorter today, but it's nice! i wear eyeliner ect, i would like to look more 'gay' so i get asked/people assume but not sure how! i wear plaid sometimes but not much! i tend to wear hoodies alot with plimmy's/converse!
i'm Bi, i like myself, i just want to be me to others! not much to ask, just how?
