Your first step towards happiness is self-acceptance. You have to accept who you are so you can move on to a better life. Once you have accepted yourself with the good and the bad it will be easier to make friends and be more social.

Another thing is to stop trying to impress others. You need to accept that no matter what we do, there are some people who doesn't like us. And that is not necessarily a bad thing because this is how you can make the difference between friends and the others.

I know this is easier said than done but you need to change your mind set if you ever want to be happy.

Take care!
