I want to stop lying befor i loose all the people i care about?

Ok, well your parents aren't being good parents by refusing to let you have help. But you don't need parental permission to see a councellor in some cases. If you have a school councellor for example. But why do you lie? Do you feel the need to impress people? Try to find the reason why you lie and work from there. Also try just to think before you talk. Before you say something, take the time and think, 'What am I saying? Is it the truth?' You may look weird, but if you get used to it it'll come naturally. Why wont your parents let you? Talk to them about it. Just let out all your feelings on them. Write them a letter if that's easier.
