Think of your heart like a emotional bank account. Just like a financial bank account, if you remove more than you have, you suffer consequences for it.
For example, you can't take out 100.00 from an account that only has 50.00. You will be come over drawn and suffer penalties until you balance out your account.
Now the same thing goes for your emotional bank account. If you keep giving out emitonally and either don't let people put back into your account or let people withdraw from your emotional bank account without them putting back, you will be come emotionally bankrupt.
The penalties for emotional bankruptcy are anger, self loathing, depression, resentment ,and finally you just shut down emotionally.
You don't want to be around any one. You don't feel good about yourself. You start to feel taken advantage of.
The only way to avoid the penalties of emotional bankruptcy is to not give out more than you have in your "account", and to not let the people in your life just take from your account with out investing something back into it. Just seomthing to think about.
