Sometimes we can be shy and reserved with others, to the point at which you build a wall around yourself and you almost stop recognizing yourself. Maybe you just need to get rid of your shyness. You're surrounded by people who love you, so you shouldn't have a problem opening up to them! Don't be afraid of being judged. They're your friends and they'll love you whatever, right?
Another theory is that sometimes we're reserved because we don't know how to express ourselves properly. It's vital you express your emotions! But whatever you do, don't take on others' emotions and opinions. Trying to attract attention and going over the top isn't going to help you maintain good relationships with the people around you.
Be yourself and others won't have a problem loving you for who you are.
