Theres moments where i want to back hand someone...

alright, I'm ranting, shocking, a girl ranting hahahaa whatever XD
A friend of mine one day just walked off school campus, i texted her and asked "why you leave???" where'd you go?" she replied "i'm so sick of school, i'm alone, and no one cares about me,and theres too much homework i'm so stressed." it took me 15 minutes to text her back, because i wanted to find the right words (without ripping her head all the way off)
heres what i replied back to her; " first of all sweet heart, you're 15, everything is going to be hard, you're growing up, trying to find your place in the world, it's not gonna come walking up to you and say 'hey i'm here well now thats over wanna party?' and you're not alone, or do we not count? ya know the people you hang out with everyday? lol, also if no one cared about you then we wouldn't be having this conversation, Also you only have 5 classes, if you're having problems or need help then just ask me, Did i mention i didn't pass the CHSPE, i'm 50 credits behind and in order to graduate on time i'm having to take up 6 more classes online, i'm not trying to have a competition with you, i'm just trying to tell you as your mum, it could be worse, don't let life kick you around, theres always a blossom underneith the ash and theres always a smile to be had under every situation. ;D

she texted back and we kept talking, she mentioned that she was close to going back to her old ways of cutting herself.
this, this makes me mad, i have no right to tell her what to do, however i did use to do this, and i told her that, but it was hard to explain to her what made me stop, i told her "i found people who began to care for me, and if i wasn't moviated to live for myself then i'd live for them, i'm living to see them laugh and smile, you're one of those people that i live for, and its hard to hear that from you when all i want for you is happiness, i think what you need to do is rethink the ways you think about things, take yourself out of that situation and look from a new perspective, like if someone makes fun of you, just stop and smile, they'll stop, and it'll throw them off, then try to make a joke, i've done this, so many times, they stop teasing you as soon as they realize you're just as good of a person as they are (however at this point you're probably better for being the mature one )

do you think i gave the right advice? o_o'
