I think that you should try and talk to your parents. If you tell them that you are feeling that way then they may feel bad and change things for you. You say that your parents are controlling your life but I am sure that that is not the case. You are a very special person and I am sure that they love you.
Suicide is not the option. There are much better ways to express your feelings. I always find that squeezing a soft ball and deep breathing helps me when I am feeling like that.
Your parents probably just want to protect you. Just having a calm chat can help to move a situation on into the future and live a happy life. Wok with them and if you are honest to them then I'm sure that they will help you.
If you ever just want to talk to me then you can, I am always here for you
