What do i do to get rid of it..

If your age bracket is correct, you're right on plan for being the center of the universe. It's a good thing; it allows you to explore the boundaries of society, test yourself, try on different personas and act freely without fear. But it can also loop around on itself to become anxiety.

time will help change that, but there are also a number of techniques you can learn for calming and de-stressing. I'd recommend www.therapistaid.com for some good self-help material and techniques. You can do this; and if you feel you can't, think about talking to a counselor or therapist. Sometimes we need to see things in different ways to get the best perspective.

stop analysing things, and focus on urself.

When you hear your judgy self, remind it that you are a work in progress, then dare to see the good you bring to the world with what you are doing in the moment.

Nothing to worry! Save your energy. I guess it is wasting somewhere else. Then will be normal.

If I say, stop analyzing things, it would not be easy for you. So read it..
