What do you think about my parents?

OK well im 14 years old about to b 15 in a cuple of months.For 3 years ive been having problems with my grandma and my mother.My mom is a funny,crazy type a person (when she wants to be) but most of the time she is very argumentive,stubborn,overproctective and jus realy immsture compared to all of my parents friends.My grandmother is the sophisticated type,but most of the time ver stuck up(exactly like people who think they are better then everyone)shes a english teacher and a very devoted christian and she doesnt listen to anything anybody says...if she hasnt been threw sumthing she doesnt care if another person has .she jus thinks there automatically crazy.Here are sum examples of both of them.One time 3 years ago i was a very obidient girl , got good grades and never did anything like a normal 12 year old,i would jus stay in he house all the tyme so i decided one day to rebell and invite a boy over and one of best friends over....she found out, secretly she had put a pc tattle thihng on my computer to see who i was talkin to and read my conversations..she did this even b4 i gave her the reason to not trust me ...after that incident ,i was on a tighter lease..I swear to god everyday was punishment.Near my 13 birthday i wanted to go out the movies wth sum friends and invite sum guy friends frum school and i also wanted to prove to my mom i was responible enough to go out..i told my mom ,she sed it was fine,now the day of my birthday everthing was flipped around,my " best friend" invited boiys i didnt even noe and they were callin the house back and forth and like my mom does she picks up the phone and listens and she found out they were 2 years older and they werent very good kkids at all. so ofcourse my mom is furious and she yells at me blaming ME for inviting these ppl and sed i was a slut and hoe , i couldnt even get a word in ..luckily we still did go ..but my mom being a sneak hides behind us spying on us the whole tyme we at the movies..that as the worst birthday ever .Now my grandmother,one time we got into a arguement about sumthin i dont remember ad she sed that im good for nuthin and i all i care about is boys and that i want her dead and that she doesnt give a **** about me anyway...i can understand if its jus in the heat of the moment yuh would say that but all the tyme...everytime my gma is sick i always take of her and i was try to be perfect for her and she makes me feel bad ,its so hard living my house ,ive been in a hospital becuz they put me on sucide watch ,i have been in and out of a childrens santurary near where i live and i have peen depressed,im jsu at withs end,ive tred everythin to try to get my parents to become better buht it jus gets worse.nobody understands me and im alone..espicailly without my father in my life ...i dont noe what elsee to do ...alot i look into myself and think mayb sumthinis wrong with me,mayb im crazii or sumthin..righ now i want to go on medication to see if i can finally b happy
