Stand up for yourself, before it becomes a problem.
A problem not just for you , but also for the people who love you ; they wouldn't know what to feel about you at a time. Or what to feel about how you feel about something. Your shifting moods and self doubt will not let it remain possible for long.
It is possible to be angry at a person for being too weak, too volatile. It is a different kind of agony which is is a product of indecision, shame and helplessness. Because no matter how much you love someone , you cannot think on their behalf. You can't tell someone to stop being weak the way you tell them to stop being a liar , a cheater or a slacker. We don't see being weak as a character flaw because we appreciate the many sweet modifications of it. But the truth is , nothing consumes our energy like loving a weak person. Not even hating a strong one. Nothing comes close to that paradox of love and anger.
