Its really does..it helps to weed out the ones your there for but its not returned and leave them at the kerb... be it family or friends!
Then learn to be there for yourself, find what makes you happy and plan your goals in life and start doing them.
Along the way new people come and go. Some stay but the core is about yourself, your life and you happiness!
You look like a beautiful young girl with a whole life ahead of you....that life is how you want to make it, imagine it and then start taking the steps to achieve it.
