Coming Out To My Family.

i'm an 18 year old girl and i've known for some considerable amount of time that i'm not exactely straight. okay, i was about 10 when i realised i liked girls as well as boys. although at the time i was confused and freaked out by it because it wasn't "normal". i remember when i was like 10 i told my mum, almost crying about a crush i had developed on a friend of mine. the crush didn't last long but i ended up telling mum a few months after it passed because i felt guilty for having those feelings. so i told my mum and, i remember being so terrified but somehow i told her. and, it was obvious she didn't believe me. when i 'confessed' i said "Mum i had a crush on......." and she replied with something like "Oh Josie you did not i can not believe i'm hearing this" as if it was almost a joke. she seemed abit amused by it if i recall. i think she thought that maybe i was confused by the whole concept of love and emotion because she fobbed it off and assured me i wasn't gay and continued with hanging the washing. i went back inside the house, and being the kid that i was i decided that yes, okay mum's right i was wrong, i'm just confused. because i knew i liked boys, and so i just put it down to me being confused with my feelings of my best friend. but in the back of mind, i just knew, that, you know it was legit, i wasn't confused. because when highschool came and puperty got intense those feelings got stronger. when i was 14 i was so confused, am i gay? am i straight? i wanted to be straight because that was the 'normal' thing to be. slang wise nowadays when we describe something as being bad we say its gay. and although i'm not prejudice and don't descriminate i was so afraid just to admit it to myself because by admitting it would mean its real and i'd have to face it. and then i'd have to face my family and i just didn't want anything to change. so i pushed it aside and ignored it, or at least tried to. and so now here i am, 18, and i'm sick of hiding it. i'm sick of pretending because now i just feel like i'm lying to my friends and family, and i only have one friend that knows the truth. the reason i've written this post is because 1. i'm up late and 2. this has been bugging me all week and as i'm up late i might as well ask the internet and so here i am. i want to tell my family the truth, i want my mum to know the truth. my family aren't homophobic, i have an uncle thats gay. but, i have a sister who doesn't really like the idea of lesbians, and i'm bi so what will she think of me? and my mum, shes kinda the same. its like they prefer the idea of gay men to gay women, maybe its because they're women themselves i dont know. i'm sorry for anyone who might be reading this for i tended to go on abit but the point i'm trying to make is, its kinda scarry. i don't want my mother to look at me differently after i tell her im bi, or my sister and the rest of my family. i don't want them to think of me differently and to be honest nothing else scares me more than that. jesus i'm sorry for going on like this, maybe i'm just over thinking this but coming out to your family is tough. so please any advice or input would be great, (and if you're going to leave hate comments dont bother because so long as your posting 'hate' i don't care for your opinion)
