My parents are too strict and I'm not living the childhood I wanted..?

im sorry about my bad english, and sorry about this long question. please read the whole thing, and I really need answers

I'm only 14, but I've been thinking back when I was around 5-10 yrs old. those were the times all of my friends always had parties and sleepovers and doing crazy childish things and going to a friend's house, but my parents never let me to any of that. like this one time I was invited to my best friend's b-day party, I made her a cute locket from scrap but I couldnt go to the party. I just explained to my parents I'd give her the gift at school, but they made me discard the gift I worked 6 hours on! they just said its a waste of time to make it and give it to her and that she's just an ordinary girl like everybody else. While all my friends were doing hw with a friend or at a birthday party, sleepover, ect...every single day im stuck in my house looking out my window watching kids have fun (im not even kidding if I had nothing to do I'd always just look out the window for hours watching other kids play outside) and my parents dont even let me outside to ride my bike in the neighborhood or something...eventually I gave up at age 11. I got use to not living a normal childhood and being trapped in my house. My life isnt even normal..my family would have breakfast at 12:00 if we had no school, skip lunch, and eat dinner at 2:00. on school days since I eat lunch at 12:00, I get home at 3:00 so my parents choose to have dinner right when I get home. I nevr even have breakfast, they just give me a huge cup of milk every morning and it always gives me stomachaches and they dont care. Now that im 14, my friends are having even more 2-3 hour house visits and short parties and theyre all inviting me to them, but I always have to turn them down because of my stupid parents. I told my best friend about my life and childhood, and she said im not living a normal childhood and that I shouldnt be trapped in my house like this. even these, days, when im all done with homework I just look out my window for hours because my parents dont allow me my phone or tv at certain times. should I just leave things as it is and keep doing the same routine since I cant change my parent's mind on letting me go to at least an important school event (they dont let me go to those either)
