How do i come over my stage fright?

what ever i do i can not sing in front of people or talk in front of people.

The only thing to do, I think, is to do it over and over and over again until it becomes second nature. Start with small groups and talk on topics you're well versed on (or sing songs that you know really well), and then work your way up. That's what Toastmaster's is good for -- repetition, repetition, repetition.
Second, remember that in most circumstances, it doesn't have to be 100% perfect. Most stagefright isn't the fear of the audience, but it's your internal fear of (a) messing up or (b) not living up to what you know as your potential. The thing is, when we're just practicing or running through things, we forget how often minor mistakes occur. But because no one's paying attention, it's no big deal.
Effectively communicating or performing just realizes that you'll never do it exactly how you want, but knowing that you'll do a great job.

Good luck,,, and practice, practice, practice!
