sometimes, you just need someone or something to make you realize you're doing the wrong things. sooner or later, you would feel worthless and unhappy. by then, you will stand up and search for your old self again. and when you find it, you'll be stronger than ever. you'll never make the same mistakes again. you'll be careful this time. you won't be hurt for the same reason again.
you'll get the hang of it... just hang in there.
before you know it, you'll be alright!
