How to cope with it?

when i was i little girl i was like an angel. i was the best one in very single cles at school, i was a good daughter and sister. i loved to help others and everyone wanted advice from me and i couldn't say no to anyone. that was until i moved to another school, met new people and started to realise that i need to live my life in a different way. my dad was seven years overboard so i practicly grew up without him, my mum was working day and night and i was fed up with tking care of everything starting with my brothers, cooking, cleaning, school and helping others. i started lying to people to make myself more interesting and exciting. in few years time i created my own world of lies and stories and now im lost in this little world of my own. i started shoplifitng, partying and i didnt care about anything and anyone. i just wanted to live. i started smoking and just enjoying my self to the ful. i even started lying to my parents about stuff and i wasnt very good at school either.
