My life is so boring maybe not to you but for me so much...?

i think im under house arest (well it feels like it) i cant leave my house not even one step out the door the only time i get to go outside is when i go to school (of course) and when thats over i have to go sright home. i cant go to friends housesgo to the park (witch is like 1 min away) my mom said i cant go outside cause she dosent want enything to happen. at school people invite me to go to partys and i never been to one cause my mom wont let me, they ask me to go to their house and i have to make a stupid excuse like "oh ummm... have to study" snd my friends cant go to my house cause all their parents wont let them and their busy. the the week ends my dad is with me but he dosent like to do enything only sleep. my brother is 10 and he gets to go to sleepovers (i never had one or been to one) he gos to partys he goes to the mall evverywhere im 14 and never leves the house . i can only wantch the little children play in front of my house throw the window i feel like im a lost soul in this house. i watch tv and use the computer but that dosent make me happy either. so can enyone tell me something to try to change my moms mind or tell me what to do.
